Understanding ADHD: Common Symptoms and Signs to Look Out For
22 / 100

ADHD, or Attention Deficit Hyperactivity Disorder, is a neurodevelopmental disorder that affects both children and adults. It is characterized by difficulties with attention, hyperactivity, and impulsivity. While it is normal for individuals to experience occasional inattention or restlessness, individuals with ADHD experience these symptoms to a greater degree, causing significant impairment in their everyday lives.

What are the common symptoms of ADHD?

ADHD symptoms can vary from person to person and can manifest differently depending on age and gender. However, there are several common symptoms that are often associated with the disorder. These symptoms can be divided into three main categories: inattention, hyperactivity, and impulsivity. 

Inattention refers to difficulties in focusing, paying attention to details, and staying organized. People with ADHD may have trouble following instructions, completing tasks, or staying on track. They may also struggle with forgetfulness, losing things, and being easily distracted.

Hyperactivity is characterized by excessive restlessness, fidgeting, and constantly being on the go. People with ADHD may have difficulty sitting still or staying quiet, often feeling the need to always be moving or talking. This can be particularly noticeable in children, as they may be seen as being overly energetic or unable to stay seated for long periods of time.

Impulsivity involves acting without thinking, often leading to hasty decisions or impulsive behavior. People with ADHD may interrupt others, have difficulty waiting their turn, and engage in risky or dangerous activities without considering the consequences. Impulsivity can also be seen in their emotional reactions, with individuals with ADHD often displaying quick and intense emotions.

It’s important to note that not all individuals with ADHD will exhibit all of these symptoms, and the severity of symptoms can vary. Additionally, symptoms may change over time, making diagnosis and treatment complex. It is recommended to consult with a healthcare professional for an accurate evaluation and appropriate management of ADHD.

When do these symptoms typically appear?

The symptoms of ADHD often appear in early childhood, with most individuals being diagnosed before the age of 12. However, in some cases, the symptoms may not become evident until later in life, particularly in individuals with milder forms of the disorder. 

The symptoms of ADHD typically manifest in early childhood, and it is common for individuals to receive a diagnosis before the age of 12. However, there are instances where the symptoms may not become noticeable until later in life, particularly in cases where the disorder presents in a milder form. This delayed onset of symptoms can make it more challenging to identify and diagnose ADHD in adulthood. It is important to note that even individuals with milder forms of the disorder can face significant challenges and may benefit from seeking professional evaluation and support.

What causes ADHD?

The exact cause of ADHD is still unknown, but researchers believe that it is likely to be a combination of genetic, environmental, and neurological factors. Studies have shown that there is a strong genetic component to ADHD, with the disorder often running in families. 


It is estimated that if a parent has ADHD, their child is at least three times more likely to have the disorder compared to a child without a family history of ADHD. This suggests that certain genes may play a role in the development of the condition.

In addition to genetics, environmental factors can also contribute to the development of ADHD. Exposure to substances like tobacco smoke, alcohol, or drugs during pregnancy has been linked to an increased risk of the disorder. Premature birth, low birth weight, and lead exposure are also thought to be potential environmental risk factors.

Neurological factors are another area of interest in understanding ADHD. Imaging studies have shown differences in the brain structure and function of individuals with ADHD compared to those without the disorder. These differences primarily involve the regions of the brain responsible for attention, impulse control, and executive functions.

It’s important to note that ADHD is a complex condition and likely involves a combination of these factors. Ongoing research aims to further unravel the role of genetics, environment, and brain function in the development and manifestation of ADHD. Understanding these underlying mechanisms is crucial for developing more effective treatments and interventions for individuals with ADHD.

How is ADHD diagnosed?

ADHD is diagnosed by healthcare professionals, typically a psychologist, psychiatrists, or paediatricians, who specialize in mental health disorders. The process usually involves a comprehensive assessment that includes gathering information from the individual, their family, and teachers or other caregivers. 

ADHD assessment is an evaluation of an individual’s behaviour, abilities, and overall functioning in order to determine whether they have Attention Deficit Hyperactivity Disorder (ADHD). This assessment can be conducted at an ADHD assessment Clinic, which specializes in diagnosing and treating ADHD. Depending on the clinic, the assessment may include cognitive tests, interviews with the individual and their family, and questionnaires about symptoms. A qualified professional such as a psychologist, psychiatrist, or developmental paediatrician will then interpret the results and make a diagnosis. Counselling is also available at ADHD Clinics to support individuals and families in managing the challenges associated with ADHD.

During this assessment, the healthcare professional will conduct interviews, use standardized questionnaires, and may also observe the individual in various environments.

The goal of the assessment is to gather information about the individual’s symptoms, behavior patterns, and overall functioning. The healthcare professional will look for symptoms of inattention, hyperactivity, and impulsivity, as well as any associated difficulties such as impulsivity or emotional regulation.

The information gathered from different sources is important to get a complete picture of the individual’s symptoms and how they impact their daily life. The healthcare professional may also rule out other possible explanations for the symptoms, such as other medical conditions or learning disabilities.

In some cases, the assessment process may also involve conducting tests to assess cognitive abilities, attention span, and executive functioning. These tests can help further understand the individual’s strengths and weaknesses and guide treatment recommendations.

Once all the necessary information has been gathered, the healthcare professional will make a diagnosis based on the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The DSM-5 provides specific criteria that must be met for a diagnosis of ADHD.

It is important to note that the diagnosis of ADHD can be complex and requires careful evaluation by a trained professional. A comprehensive assessment ensures that the diagnosis is accurate and that appropriate treatment and support can be provided to help manage symptoms and improve functioning.

What treatments are available for ADHD?

ADHD is a chronic condition that cannot be cured, but it can be effectively managed with appropriate treatment. The goal of treatment is to reduce the symptoms and improve functioning in various areas of life, such as school, work, and relationships. 

 Treatment for ADHD typically involves a combination of medication, therapy, and education. Medications, such as stimulants or non-stimulants, can help control impulsivity and improve attention and concentration. However, it is important to note that medication alone may not be enough and should be combined with therapy.

Therapy options for ADHD include behavioral therapy, cognitive-behavioral therapy, and psychoeducation. These therapies aim to teach individuals with ADHD skills to better manage their symptoms, improve organizational skills, and develop healthy coping mechanisms. Therapy can also help individuals address any emotional or behavioral issues that may be associated with ADHD.

In addition to medication and therapy, education and support are crucial for managing ADHD. This involves educating individuals with ADHD, as well as their families and teachers, about the condition and its impact on daily life. Support groups can also provide a valuable platform for individuals with ADHD to connect with others, share experiences, and learn from one another.

It is important to understand that ADHD is a lifelong condition, and ongoing management is necessary. Regular check-ups with healthcare professionals, medication adjustments, and consistent therapy are essential components of effective ADHD management. Additionally, creating a structured and organized environment, establishing routines, and setting realistic goals can all contribute to better outcomes for individuals with ADHD.

With the right combination of treatments and support, individuals with ADHD can lead fulfilling lives and achieve success in various aspects of life. It is important to remember that each individual is unique, and finding the most suitable treatment plan may require some trial and error. Patience, understanding, and a collaborative approach between the individual, their loved ones, and healthcare professionals are essential for managing ADHD effectively.


ADHD is a complex disorder that can have a significant impact on individuals’ lives, but with proper diagnosis and treatment, individuals with ADHD can lead fulfilling and successful lives. It is important to be aware of the common symptoms of ADHD and seek professional help if you suspect that you or someone you know may be affected. Early intervention and appropriate support can make a significant difference in managing the symptoms and improving overall functioning.
