What is the definition and Subtypes of ADHD?

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity. Here, we aim to provide you with an in-depth understanding of ADHD by exploring its definition, prevalence, subtypes, etiology, diagnostic criteria, associated features, co-morbidities, and treatment approaches. Additionally, we will examine the impact of ADHD on individuals, families, and society, and discuss strategies for managing and supporting individuals with ADHD. It is common in school-aged children and young children.  ADHD can be classified into three subtypes:

  • predominantly inattentive
  • predominantly hyperactive-impulsive
  • combined presentation

What are the symptoms of hyperactivity & ADHD?

  • short attention span
  • impulsive behaviors
  • difficulty with social skills
  • being easily distracted
  • making careless mistakes for example in schoolwork
  • being forgetful and losing things
  • unable to listen to or carry out instructions
  • fidgeting
  • acting without thinking
  • risk of developing substance use disorder or substance abuse
  • possible co-existance with Tourette syndrome

What is the causes and risk factors of ADHD?

The etiology of ADHD is multifactorial, involving a combination of genetic, environmental factors, and neurobiological factors. Genetic studies, prenatal and perinatal factors, brain structure and function, neurotransmitter imbalances, and psychosocial influences are discussed in this section.

Traumatic brain injury (TBI) is a frequent cause for hospitalization in young children and teenagers. It is associated with developing mental conditions, including secondary ADHD which is a form of ADHD that develops following an injury.

What are the diagnostic criteria for ADHD?

The diagnosis of ADHD is based on specific criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).

What are the associated types of ADHD and Co-morbidities for ADHD?

There are three major types of ADHD:

  • ADHD, combined type. This, the most common type of ADHD. It is characterized by impulsive and hyperactive behaviors as well as inattention and distractibility
  • ADHD, impulsive/hyperactive type
  • ADHD, inattentive and distractible type

ADHD often co-occurs with other mental health conditions and learning disorders. Common co-morbidities include oppositional defiant disorder (ODD), conduct disorder (CD), anxiety disorders, mood disorders, and learning disabilities.

How is ADHD assessed and diagnosed?

The assessment and diagnosis of ADHD involve a comprehensive evaluation that includes clinical interviews, rating scales, behavioral observations, and collaboration with parents, teachers, and other relevant individuals. This section outlines the assessment process and the importance of obtaining a thorough developmental and medical history.

What are the ADHD treatment options?

ADHD management typically involves a multimodal approach that includes:

  • behavioral therapy
  • behavior management
  • pharmacological interventions
  • psychotherapy
  • psycho-education
  • school-based support

Behavioral Interventions

Behavioral interventions, such as parent training, behavior modification techniques, and classroom management strategies aim to improve self-control, organizational skills, and adaptive behaviors.

Pharmacological Interventions

Stimulant medications (e.g., methylphenidate, amphetamines) and non-stimulant medications (e.g., atomoxetine, guanfacine) are commonly prescribed to manage ADHD symptoms. This section discusses the mechanisms of action, benefits, side effects, and considerations for medication use.

Psycho-education and Parent Training

Psycho-education provides individuals and their families with information about ADHD, its impact, and strategies for managing symptoms. Parent training programs empower parents with knowledge and skills to support their child with ADHD effectively.

School-Based Interventions

Collaborating with schools and implementing classroom accommodations, specialized instruction, and Individualized Education Plans (IEPs) or 504 Plans can support academic performance and address the specific needs of students with ADHD.

Multimodal Treatment

Combining different treatment modalities, such as behavioral interventions and medication, has been found to be more effective in managing ADHD symptoms than using a single approach alone.
