• Hyperactivity: Excessive movement or fidgeting, inability to stay seated, and restlessness.
• Impulsivity: Hasty actions without forethought, interrupting others, and difficulty waiting for one’s turn.

These symptoms can vary in intensity and may present differently across individuals.

Diagnosis of ADHD.

Diagnosing ADHD involves a comprehensive evaluation by healthcare professionals, considering various factors to ensure an accurate diagnosis.

Diagnostic Criteria:

• Symptom Duration: Symptoms must be present for at least six months and inappropriate for the individual’s developmental level.
• Age of Onset: Several symptoms should have been evident before the age of 12.
• Settings: Symptoms must be present in two or more settings (e.g., home, school, work).
• Impact: There should be clear evidence that the symptoms interfere with or reduce the quality of social, academic, or occupational functioning.

Assessment Process:

• Clinical Interviews: Gathering detailed personal and family history.
• Behavioral Questionnaires: Standardized tools to assess the frequency and severity of symptoms.
• Medical Examination: To rule out other potential causes of symptoms.

Treatment Options.

Managing ADHD typically involves a multimodal approach, combining medication, behavioral therapies, and lifestyle modifications.

Medications:

• Stimulants: Such as methylphenidate and amphetamines, are commonly prescribed and have been shown to be effective in reducing core symptoms.
• Non-Stimulants: Options like atomoxetine or certain antidepressants may be used, especially if stimulants are not suitable.

Behavioral Therapies:

• Cognitive Behavioral Therapy (CBT): Helps individuals develop coping strategies and address negative thought patterns.
• Behavioral Interventions: Techniques aimed at modifying disruptive behaviors and enhancing organizational skills.

Lifestyle Modifications:

• Regular Exercise: Physical activity has been shown to improve attention and reduce hyperactive behaviors.
• Structured Routines: Establishing consistent daily schedules can aid in managing symptoms.
• Dietary Considerations: Some studies suggest that certain dietary changes may benefit individuals with ADHD, though more research is needed.

Real-Life Experiences and Case Studies.

Understanding ADHD through personal stories provides valuable insights into the challenges and triumphs associated with the condition.

Case Study 1: Late Diagnosis in Adulthood.

Claire Quant and Kate Whitley spent much of their lives feeling like failures due to undiagnosed ADHD. Both women struggled with concentration, anxiété, and social interactions as children, leading to academic and social difficulties. It wasn’t until their 50s that they received ADHD diagnoses, which provided clarity and validation for their lifelong challenges. Post-diagnosis, Claire and Kate found solace and support, helping them manage their symptoms and improve their quality of life.

Case Study 2: Impact of ADHD on Life Expectancy.

A recent study by University College London has revealed that individuals diagnosed with ADHD in the UK have a significantly reduced life expectancy compared to their peers. The study found that men with ADHD have their life expectancy reduced by 6.78 years, while women lose 8.64 years. Researchers used the life-table method to analyze data from 30,000 adults in the UK, discovering that those with ADHD are more likely to suffer from various health conditions, including diabetes, high blood pressure, anxiety, and depression, which contribute to their higher mortality rate.⁽¹⁾
