Why Can't I Focus on Anything


Not being able to focus or concentrate is quite a common problem. In therapy, clients sometimes say things like “I can’t focus on anything”. There are many reasons this happens. Indeed, it’s quite normal to experience a lapse in our ability to focus from time to time. But when it goes on for too long, it’s important to understand that ironically, this deserves our attention. If you’re already struggling with the ability to concentrate, this article might test your attention, but if you muster on, you’ll learn about the signs, diagnosis, and treatment, as well as what to do when you can’t focus. In so doing, you can improve cognitive and day-to-day functioning and therefore take more enjoyment from simple tasks like reading a book, or having a conversation.

Signs Of Having Trouble Focusing

Being Unable to Remember

One sure sign that there might be problems with concentration is if the thought “my mind is all over the place” has occurred to you, especially if this is a frequent thought. When our minds are not being able to focus, we can struggle with memory as well. This is because when attention is scattered, the brain is unable to encode memories. This lack of focus means the transfer of information to long-term memory is impaired, resulting in forgetfulness.

Being Unable to Concentrate

If you’ve noticed that focusing or paying attention to tasks is a challenge then you will also notice that you’re struggling to engage in all kinds of things. This can mean that your focus shifts and you’re distracted easily. This inability to concentrate is because the neural networks that are responsible for sustained attention are compromised, so cognitive performance, that is., concentration becomes affected. This can lead to reduced productivity, forgetfulness, and difficulties completing tasks to a good standard.

Lack of Energy

When you can’t think clearly and are not able to focus or concentrate, you might try to work harder to focus but this causes mental fatigue. Or, sometimes it’s the lack of energy that can cause difficulties with concentration. This is because when we’re fatigued our brain doesn’t have the necessary resources to sustain focus and attention. When this happens you might notice it as mental fogginess, decreased motivation, and increased susceptibility to distractions, all of which affect focus.

Brain Fog

What exactly is brain fog? Brain fog describes the feeling of mental cloudiness or cognitive confusion. When this feeling of ‘haziness’ occurs, you’ll notice you can’t focus on anything, have problems with focusing and concentrating, and with remembering things. All of these can be frustrating and affect daily functioning. This is why it is important to understand the causes, as there are many.

Inability to Make Decisions

Another possible sign of a lack of concentration and focus in adults is when you notice that you’re unable to make decisions, sometimes even simple ones. This can happen as a sign of impaired concentration because to make effective decisions we have to be able to gather, process, and evaluate information. When focus is compromised, it becomes quite challenging to take in important and relevant details, weigh up pros and cons, and arrive at a clear choice. Instead we might experience hesitation, indecision, or impulsivity, all of which indicate a struggle to focus and think critically.

Inability to Finish Tasks in a Timely Manner

If you notice you’re finding it hard to finish tasks as intended, you may be experiencing a lack of focus. Indeed, we need to be able to concentrate for sustained periods and manage our time to complete tasks to deadlines. But when focus is hard to achieve, it takes longer to finish things because of distractions, procrastination, or a scattered thought process. This can lead to a sense of frustration due to the inability to concentrate and achieve goals.

Making Careless Mistakes

Making careless mistakes and oversights can be a clear sign of impaired focus because it suggests a lack of attention to detail. When we are not being able to focus, we are more likely to overlook important information, skip steps, or misinterpret instructions.  All of these lead to mistakes. These lapses in accuracy and precision may be telling you there’s a problem with maintaining focus which is a sign of cognitive challenges.

Frequently Losing Things

If you’re asking yourself “Why can’t I focus?” when you’re losing objects, it might be the ability to concentrate that’s been lost. This is because when we struggle to focus, we might not pay enough attention to where we put things. This means that when we try to remember where we last used them, we simply just can’t. This forgetfulness and disorganisation causes misplacement as our brains struggle to retain and process information about the locations of things.

Difficulty Sitting Still

Difficulty sitting still can be a sign of strained focus, especially in children and adults with conditions like attention-deficit hyperactivity disorder (ADHD). Restlessness and an inability to remain seated, or focused on a task can demonstrate challenges in maintaining attention. This can look like fidgeting, where people shift positions often due to a constant need for movement to remain engaged, but all of these interfere with the ability to focus effectively.


Procrastination is often a sign of difficulties with focus as well. When people struggle to focus on a task, they may put off starting it or repeatedly delay its completion. This procrastination is a coping mechanism, as it temporarily relieves the discomfort of trying to focus. However, it can lead to stress, anxiety, and even depression due to the inability to accomplish goals and the ways in which this can hinder progress in various aspects of life.

Causes Of Being Unable To Concentrate

Internal Distractions

Internal distractions can significantly undermine concentration. Internal distractions take attention away from the task at hand and there are many factors that can contribute, some of these include:

Worrying: If you are worrying about things, these worries can move your mind away from things in the day-to-day. Worrying takes cognitive load, or mental bandwidth, making it difficult to concentrate as your mind is preoccupied with worries instead of focusing on what you need to.

Daydreaming: Another form of internal distraction is daydreaming. When your mind unintentionally wanders, you move your focus from what you’re trying to do, to unrelated thoughts, scenarios, or fantasies.

Multitasking: This is when we try to distribute our attention to multiple things which dilutes the focus we can place on any one thing. This is often counterproductive as it leads to reduced efficiency and increased errors.

Physical Discomfort: When we’re hungry, tired, or in pain, we experience internal distractions. This is because our focus shifts to our physiological needs, making it difficult to pay attention to other things.

External Distractions

External distractions are external stimuli that divert attention away from the think one is trying to concentrate on. Such distractions can significantly impair one’s ability to focus and include various factors:

Noise: Loud or persistent noise from traffic, construction, or co-workers can disrupt concentration. These make it challenging to keep attention on tasks that require mental focus.

Technology: The constant notifications, emails, and social media updates from smartphones, tablets, and computers can be highly distracting. These devices can pull us away from work or studies. This is especially true because of the dopamine we experience from these distractions – which can cause an oversaturation of the hormone.

People: Interactions with colleagues, friends, or family members can interrupt concentration. Even brief conversations or interruptions can break the flow of thought.

Environmental Factors: Poor lighting or uncomfortable temperatures or seating arrangements are external distractions that can cause internal distractions like physical discomfort which can reduce the ability to concentrate effectively.

Visual Clutter: A cluttered or disorganised workspace can be visually distracting. It can draw attention away from the task at hand and make it difficult to stay focused.

Proximity to Entertainment: Access to TV, video games, or other sources of entertainment in the vicinity can be tempting distractions, particularly when we are looking for excuses to escape and procrastinate.

Intrusive Sounds or Smells: Sudden or unpleasant sounds and smells in the environment can disrupt concentration by capturing attention and triggering emotional responses.

Lack of Motivation

An internal factor that commonly affects concentration is demotivation. When we experience a lack of motivation for something we simply cannot concentrate or give it the attention and focus needed. If you don’t feel enthused toward something, you won’t experience the sense of purpose that’s needed to engage mentally. This lack of motivation causes procrastination, so tasks are delayed and left incomplete because the ability to problem-solve is also absent when we can’t focus. Demotivation also causes the mind to wander and indulge in distracting thoughts and we can give up easily and move on to more tempting activities.

Lack of Sleep

Sleep is restorative and even though scientists still don’t truly understand why we need it, we do know that a lack of sleep can lead to various cognitive and attention-related issues. Sleep deprivation can cause physical and mental fatigue, making it challenging to stay alert and focused. Because of the reduction in cognitive function, the ability to process information, make decisions, and solve problems is compromised. Our functioning becomes slower and less efficient making reaction times slower which can cause problems with quick thinking and decision making. Attention-span is shortened as well, making it difficult to concentrate on tasks for extended periods. Memory is consolidated during sleep so a lack of sleep can also cause forgetfulness. We also have lower tolerance and may therefore experience irritability, frustration, and mood swings. These emotional changes can also affect concentration. In extreme cases of sleep deprivation, people can experience brief, involuntary episodes of “microsleep,” in which consciousness is lost for a few seconds, even while trying to remain awake and attentive.

An Unhealthy Diet

Research suggests that gut microbiome plays a role in cognitive function so it’s no surprise that an unhealthy diet affects brain health and concentration. Indeed, a diet lacking essential vitamins, minerals, and omega-3 fatty acids impairs brain function because these nutrients play a vital role in cognitive processes and neurotransmitter function. Deficiencies can lead to reduced mental clarity and focus. Blood sugar levels spike and crash when consuming high-sugar or processed foods. These fluctuations can lead to feelings of irritability, fatigue, and difficulty concentrating during the post-meal energy slump. This impact means the energy required to be alert and engaged is not available. A diet high in processed foods, sugar, and unhealthy fats, can also contribute to chronic inflammation. Inflammation has been linked to cognitive impairments and may interfere with concentration. Unhealthy food choices have also been associated with an increased risk of mental health issues like depression and anxiety, which further disrupt concentration. In addition, processed and sugary foods may not provide adequate hydration, leading to impaired focus, memory, and overall cognitive function.

Vitamin Deficiency

Deficiencies in certain key vitamins, can significantly impact concentration and cognitive function. For example:

Vitamin B12 plays a crucial role in maintaining healthy nerve cells and producing red blood cells. A deficiency in B12 can lead to cognitive problems, including difficulty concentrating, memory lapses, and even mood changes.

Vitamin D is important for brain health, and its deficiency has been associated with poor concentration, reduced attention span, and increased risk of conditions like depression.

Vitamin C is an antioxidant that supports brain health. A deficiency may lead to symptoms like fatigue and irritability, which can interfere with concentration and cognitive function.

Folate (Vitamin B9) is essential for normal brain function and the synthesis of neurotransmitters. A deficiency can result in cognitive issues, including poor concentration and forgetfulness.

Vitamin E is an antioxidant that protects brain cells from oxidative damage. A deficiency may contribute to cognitive decline and difficulties with memory and concentration.

Vitamin K is involved in brain cell membrane formation and function. A deficiency may affect cognitive abilities, although it is less common than deficiencies in other vitamins.

Thiamine (Vitamin B1) is essential for brain energy metabolism. Severe thiamine deficiency can lead to neurological problems, including confusion, memory problems, and difficulty concentrating.

Stress and Burnout

Overwhelm: Stress and burnout significantly impact the ability to concentrate and focus because when we’re stressed or experiencing burnout, our minds will often feel overwhelmed with worries and tasks. This cognitive overload makes it difficult to organise thoughts, prioritise, and stay on task.

Chronic anxiety: Our brains become preoccupied with stressors, leaving little mental capacity for other things. Because stress creates a constant and heightened state of alertness and worry about the stressor or its consequences. This chronic state of anxiety makes it challenging to focus on anything else, as we keep returning to the source of stress.

Exhaustion: Burnout, in particular, is characterised by emotional exhaustion. When you’re emotionally drained, it becomes difficult to maintain the emotional resilience needed to concentrate and engage fully in tasks.

Cognitive impairment: And stress can narrow your cognitive focus, making it harder to see the bigger picture and think creatively. This can hinder your ability to solve complex problems that require flexible thinking. Stress can also lead to a decreased attention span, making it challenging to sustain focus on a single task for an extended period.

Physical problems: Stress and burnout can also cause physical symptoms like headaches, muscle tension, and fatigue, these internal distractions make it harder to concentrate.

Demotivation: Furthermore, stress and burnout can lead to a lack of motivation. You may start to feel that your efforts are futile or that you’re too overwhelmed to make progress. This demotivation can result in procrastination and a further decline in concentration.

Memory issues: Chronic stress can also impair both short-term and long-term memory, making it challenging to retain and recall information, and hindering concentration.

Sleep problems: In addition stress and burnout can disrupt sleep patterns. Poor sleep quality or insufficient sleep can lead to daytime drowsiness and difficulties maintaining focus.

Low Self-Esteem: Negative self-talk and self-doubt can happen during times of stress and burnout as well. If you’re constantly criticising yourself or doubting your abilities, it can undermine your confidence and concentration.

Hormonal Imbalances

Hormones are chemical messengers that play a crucial role in regulating various bodily functions, including brain function so when these hormones are out of balance, it can lead to concentration problems. Here’s how:

Thyroid Hormones: Thyroid hormones, including thyroxine (T4) and triiodothyronine (T3), are essential for regulating metabolism and brain function. An underactive thyroid (hypothyroidism) can result in symptoms like fatigue, brain fog, and difficulty concentrating. On the other hand, an overactive thyroid (hyperthyroidism) can lead to anxiety and racing thoughts, which can also affect concentration.

Sex Hormones: Hormonal fluctuations during the menstrual cycle, pregnancy, and menopause or andropause can affect mood and cognitive function. Some people may experience difficulty concentrating, memory problems, and mood swings during these hormonal changes.

Insulin: Insulin regulates blood sugar levels, and fluctuations in blood sugar can affect brain function. When blood sugar levels drop too low (hypoglycemia) or spike too high (hyperglycemia), it can result in difficulties with concentration, focus, and mood.

Cortisol: Cortisol, often referred to as the stress hormone, plays a role in regulating stress responses. Chronic stress can lead to elevated cortisol levels, which can impair cognitive function and memory. It can also contribute to anxiety, making it difficult to concentrate.

Adrenal Hormones: Alongside cortisol, the adrenal glands also produce hormones such as adrenaline, which are also involved in the body’s stress response. Prolonged stress or adrenal fatigue can disrupt the balance of these hormones, leading to fatigue, anxiety, and concentration problems.

Sexual Hormones: Testosterone, oestrogen, and progesterone play roles in mood and cognitive function in both men and women. Imbalances in these hormones can lead to mood swings, irritability, and difficulties with concentration.

Growth Hormone: Growth hormone is essential for overall growth and repair of tissues, including the brain. A deficiency in growth hormone can lead to fatigue, cognitive impairment, and reduced attention span.

Medical Causes Of An Inability To Focus


Attention Deficit Hyperactivity Disorder impairs the ability to focus due to persistent symptoms like inattention and impulsivity. Individuals with ADHD frequently struggle to sustain attention on tasks or activities, often becoming easily distracted by external stimuli or racing thoughts. This difficulty in maintaining concentration can hinder productivity and academic performance. Impulsivity further disrupts focus, as individuals may act on immediate impulses, interrupting their concentration. While medication and behavioural therapy can help manage ADHD symptoms, the condition fundamentally challenges an individual’s capacity to concentrate, affecting daily tasks and goal attainment.


If you’re anxious and can’t focus on anything it’s likely because anxiety can disrupt the ability to focus. When experiencing anxiety, the mind is preoccupied with excessive worry, fear, or nervousness, diverting attention away from the task at hand. Physical symptoms like rapid heart rate, restlessness, and muscle tension can make it difficult to concentrate. Additionally, anxiety often triggers a heightened state of alertness, causing us to become hyper-vigilant about potential threats, further distracting us from tasks. Racing thoughts and constant rumination can impair cognitive processes and problem-solving abilities.


When people are depressed they often experience a pervasive sense of sadness, hopelessness, and emotional numbness, which can make it challenging to engage in tasks and concentrate so depression can significantly impact the ability to focus. Fatigue and low energy levels are common symptoms of depression as well, these lead to reduced motivation and difficulty keeping attention on activities. Negative thought patterns and self-criticism can exacerbate the ability to focus by generating a cloud of pessimism. Depression’s cognitive symptoms, often referred to as “brain fog,” include poor concentration, memory problems, and slowed thinking.


A concussion can have a profound and immediate impact on focus and concentration. It is a type of traumatic brain injury that disrupts normal brain function temporarily. Common symptoms include difficulty focusing, confusion, memory problems, and attention deficits. These cognitive impairments can be pronounced shortly after the injury and may persist for days, weeks, or even months, depending on the severity of the concussion. Concussions affect various cognitive processes, such as attention span, information processing speed, and working memory. Visual disturbances, headaches, and sensitivity to light or noise can also hinder concentration.

When To Seek Professional Help

Seeking professional help for concentration difficulties is important when it significantly interferes with your daily life and well-being. For example, if you consistently struggle to focus or concentrate on anything, and these difficulties are severe, and last for an extended period. It’s also important to seek help if you notice that your troubles focusing are affecting your work, education, or relationships. Another warning sign indicating need for professional help is when you notice a decline in your ability to perform tasks that you could previously handle easily (including a drop in work or academic performance, forgetting important appointments, or difficulty with basic daily tasks). If concentration problems are accompanied by other concerning symptoms like mood changes (e.g., depression or anxiety), memory issues, fatigue, or physical health problems, consulting a healthcare professional is also advisable. If you experience a sudden and unexplained onset of concentration difficulties, it may be related to a medical condition, medication side effects, or a recent head injury, warranting immediate evaluation. If concentration issues cause significant personal distress, frustration, or anxiety, it’s a good indicator for seeking professional support.

How is Being Unable to Concentrate Diagnosed?

Not being able to focus and concentrate is usually a symptom of another condition or disorder. There are various ways it will become apparent. For example, if you visit your healthcare provider, they’ll ask about your symptoms, medical history, and any potential underlying causes. Sometimes a physical examination may be necessary to rule out any medical conditions that could be affecting your ability to concentrate, such as thyroid problems or nutritional deficiencies. If there’s suspicion of a medical cause, blood tests or other laboratory investigations may be ordered to check for conditions like anaemia, thyroid dysfunction, or hormonal imbalances. In cases of suspected brain injury or neurological conditions, neuroimaging such as CT scans or MRI scans may be recommended.

Psychologists may use standardised tests and questionnaires to assess cognitive function, attention, and concentration. These assessments help determine the extent of the problem and whether it fits criteria for conditions like Attention Deficit Hyperactivity Disorder (ADHD) or other cognitive disorders. Information from family members, teachers, or colleagues can be valuable in assessing the impact of concentration difficulties on daily functioning. The conclusion is typically made based on a combination of these assessments and considering the overall clinical picture. Once diagnosed, appropriate treatment options can be explored, which may include therapy, medication, lifestyle modifications, or addressing underlying medical conditions.

How Is Being Unable To Focus Treated? (Outside Therapy & Medication Intervention)

Exercise Daily

Exercise increases blood flow to the brain, delivering more oxygen and nutrients. It also releases neurotransmitters like dopamine, serotonin, and endorphins, enhancing mood and focus – great when you can’t focus. Regular physical activity supports cognitive functions, improves attention span, and reduces stress, contributing to better concentration and mental clarity.

Eat Well

Eating well provides the brain with essential nutrients and energy it needs to function optimally. A balanced diet supports stable blood sugar levels, preventing energy crashes that can affect concentration. Nutrient-rich foods like fruits, vegetables, and Omega-3 fatty acids support brain health, enhancing focus and cognitive performance.

Take Care of Basic Needs

Taking care of basic needs, including sleep, hydration, and stress management, is crucial for concentration. Proper sleep allows the brain to recharge, improving cognitive function. Staying hydrated helps maintain alertness. Stress management techniques reduce distractions and promote mental clarity, enhancing overall focus and productivity.


Meditation enhances concentration by training the mind to focus on the present moment. It reduces mental clutter and distractions, promoting mindfulness. Regular practice improves attention span, cognitive control, and the ability to redirect focus, ultimately enhancing concentration and mental clarity in daily tasks and activities.

Turn Off Your Phone

Turning off your phone or putting it on silent mode can significantly improve concentration by eliminating distractions. It prevents notifications, calls, and messages from interrupting your work or tasks. Without the constant urge to check your phone, you can maintain a more focused and productive work environment, enhancing your ability to concentrate on what’s important.

Skip the Coffee

Skipping excessive coffee consumption can positively impact concentration. While caffeine can provide a temporary energy boost and alertness, excessive intake can lead to jitteriness, anxiety, and disrupted sleep, all of which hinder concentration. Reducing coffee or avoiding it in the afternoon promotes steadier focus and prevents energy crashes, supporting better concentration.

Use The Pomodoro Technique

The Pomodoro Technique is a time management method that enhances concentration by breaking work into focused intervals (usually 25 minutes) followed by short breaks. It combats mental fatigue by providing structured work periods, preventing burnout, and maintaining optimal focus during work sprints. The technique encourages sustained attention, improving productivity and concentration on tasks.


Concentration difficulties are a prevalent issue with far-reaching impacts. Understanding the signs, causes, and consequences of these challenges is crucial. From memory lapses to lack of motivation, various factors can disrupt our ability to focus, including internal distractions like worry and external ones such as technology or noisy environments.

Psychological conditions like ADHD, anxiety, depression, or concussions can compound these challenges. Knowing when to seek professional help is essential, as it allows for a comprehensive evaluation and diagnosis. Once diagnosed, individuals can explore various treatment options, from exercise and nutrition to mindfulness techniques and time management strategies like the Pomodoro Technique.

By addressing the root causes and implementing effective strategies, individuals can reclaim their cognitive function and rediscover the joy in daily activities. Whether it’s regaining the ability to concentrate at work or finding pleasure in reading a book, the journey toward improved focus and mental clarity is within reach for those willing to explore these insights and solutions.
