What is ADHD?
Attention-Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition seen in children and adults marked by persistent issues with attention, impulsiveness, and overactivity. According to research, individuals with ADHD might find it challenging to concentrate, manage impulsive actions, and are generally more active than their peers.
ADHD Full Form:
If we talk about the full form of ADHD, it is Attention-Deficit/Hyperactivity Disorder that emphasising the combined challenges of attention difficulties and hyperactive behaviour.
Types of ADHD
ADHD is divided into three primary classifications based on the dominant symptoms:
Predominantly Inattentive Presentation:
Individuals with this form often face significant challenges with maintaining focus and organisational skills. They may appear to be forgetful, get distracted easily, and struggle with following directions or completing assignments.
Predominantly Hyperactive:
Impulsive Presentation: This form involves excessive activity and difficulties with impulse control. Symptoms include incessant talking, an inability to sit still, and challenges with waiting turns in various situations.
Combined Presentation:
The most frequently encountered form of ADHD, this type includes symptoms of both inattention and hyperactivity-impulsivity.
Each type of ADHD presents its own set of challenges and symptoms, impacting various aspects of a person’s life.

What are the causes of ADHD?
According to research, While the precise origins of ADHD remain uncertain, it is believed to stem from a blend of genetic, neurological, and environmental factors:
Genetics:
A familial trend suggests a genetic predisposition to ADHD. Having family members with ADHD increases the likelihood of developing the condition.Brain Anatomy and Neurochemistry:
Variances in brain structure and the function of neurotransmitters, notably dopamine and norepinephrine, are thought to influence ADHD behaviours.Environmental Influences:
Exposure to environmental toxins during prenatal stages, preterm birth, and reduced birth weight are recognized risk enhancers for ADHD.
Premature birth or being underweight at birth can increase the likelihood of developing ADHD, possibly affecting brain development and functioning. Recognizing these contributing factors aids in the creation of preventive measures and effective management strategies for ADHD. It’s essential to understand ADHD meaning as it pertains to both the medical and behavioural challenges associated with this disorder.
What are the symptoms of ADHD?
ADHD manifestations vary with the subtype present. Common symptoms for each type include:
Inattentive Symptoms:
Challenges with detailed orientation leading to errors in schoolwork or other tasks, difficulty sustaining focus in activities or discussions, forgetfulness in daily routines, and avoidance of mentally demanding tasks.
Hyperactive Symptoms:
Persistent fidgeting or squirming, inability to remain seated in expected settings like classrooms, excessive talking, and interruptions during conversations.
Impulsive Symptoms:
Rash actions without considering consequences, frequent interruptions in conversations, challenges in waiting turns in activities, and impulsive decision-making that may lead to errors or mishaps.
Occasional symptoms of inattention, hyperactivity, or impulsivity do not confirm an ADHD diagnosis; the persistence and impact of these symptoms on daily functioning are crucial for diagnosis.

How can you prevent ADHD?
According to WebMD, While preventing ADHD entirely may not be possible, certain strategies can mitigate its risk or lessen its severity: Healthy Pregnancy: Adopting a healthy lifestyle during pregnancy can influence foetal development. Avoiding harmful substances like alcohol and tobacco can promote optimal brain development and decrease ADHD risks.
Early Intervention:
Timely recognition and management of developmental delays or behavioural issues can enhance outcomes for children, potentially reducing ADHD severity. Environmental Safety: Ensuring a toxin-free and stimulating environment is crucial for child development. Reducing exposure to harmful substances like lead and maintaining a clean living area supports healthy brain growth.
Nutritional Support:
A diet rich in essential nutrients, including omega-3 fatty acids from sources like fish, nuts, and seeds, is beneficial for brain health and overall cognitive and behavioural functions. Parenting Strategies: Employing effective parenting techniques, such as clear communication, structured routines, and positive reinforcement, can help manage and improve ADHD-related behaviours.
How to diagnose ADHD?
Diagnosing ADHD involves a comprehensive assessment by healthcare professionals, typically including the following steps:
Medical History Review:
The doctor will gather information about the individual’s medical history, symptoms, and family history of ADHD or related disorders. This helps in understanding the context and potential genetic factors contributing to the symptoms.Physical Examination:
A physical exam is conducted to rule out other medical conditions that may mimic ADHD symptoms or contribute to behavioural issues. This helps ensure that any underlying health concerns are addressed appropriately.Diagnostic Criteria:
The doctor will refer to specific criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to diagnose ADHD. These criteria include a certain number of symptoms of inattention and/or hyperactivity-impulsivity that have been present in multiple settings (e.g., home, school, social settings) for at least six months. For an official diagnosis, ADHD ICD 10 codes are often used in clinical settings to categorise and record the condition.Behavioural Assessment:
Parents, teachers, and other caregivers may be asked to complete behaviour rating scales or questionnaires to provide additional information about the individual’s symptoms and behaviour patterns. This comprehensive input from multiple sources helps in forming a clear picture of the individual’s functioning.Rule Out Other Conditions:
ADHD symptoms can overlap with other conditions, such as learning disabilities, anxiety disorders, or mood disorders. Therefore, additional assessments or tests may be conducted to rule out these possibilities and ensure an accurate diagnosis.
A thorough evaluation is crucial for an accurate diagnosis and to develop an appropriate treatment plan tailored to the individual’s needs.
What are the complications of ADHD?
If ADHD is not effectively managed, several complications can arise, impacting educational, social, and emotional spheres:
Educational Obstacles:
The challenges of focusing and task completion may undermine academic performance, leading to subpar grades, unmet deadlines, and educational dissatisfaction.Social Challenges:
The impulsive and hyperactive behaviours typical of ADHD can complicate social interactions. It might result in frequent interruptions, difficulty waiting for one’s turn, or challenges in forming and maintaining friendships, often escalating to social conflicts and a sense of being isolated.Impaired Self-Confidence:
Repeated criticisms and continuous struggles in school and social life can erode self-confidence. Persistent feelings of failure or misperception can cultivate a poor self-image and a sense of inadequacy.Propensity for Risky Behaviour:
In an attempt to manage their symptoms, adolescents and adults with ADHD may resort to high-risk activities. This might include substance misuse, irresponsible driving, or unsafe sexual behaviours without adequate consideration of the potential repercussions.Emotional Challenges:
The ongoing effort to manage ADHD can be overwhelming. Regular confrontations with personal limitations and societal expectations may induce significant stress, anxiety, and depression.
Early intervention and appropriate treatment can help minimise these complications and improve overall quality of life for individuals with ADHD.

What are the treatment options for ADHD?
ADHD treatment typically involves a combination of behavioural interventions, educational support, and sometimes medication:
Behavioural Therapy:
Techniques such as behaviour modification, where positive behaviours are encouraged and rewarded, can be effective. Parent training helps caregivers learn strategies to manage behaviour at home. Social skills training teaches individuals how to interact more effectively with others. ADHD therapies often encompass these behavioural strategies.Educational Support:
For students with ADHD, individualised education plans (IEPs) can provide specific accommodations and support in the classroom. This might include extra time for assignments, seating arrangements, or specialised teaching methods.Lifestyle Changes:
Regular physical exercise can help reduce hyperactivity and improve concentration. Adequate sleep is essential for overall well-being and can help manage ADHD symptoms. A balanced diet rich in nutrients like omega-3 fatty acids (found in fish) and avoiding excessive sugar and processed foods can also support brain health.Counselling:
Therapy, such as cognitive-behavioural therapy (CBT), can help individuals and families develop coping strategies and address emotional challenges associated with ADHD. Counselling can also provide support for managing stress and improving relationships.
