What is Adult ADHD?

ADHD is characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with functioning and development. In adults, these symptoms may manifest differently than in children, often appearing as:

  • Difficulty organizing tasks and activities
  • Trouble meeting deadlines or following through on commitments
  • Frequent forgetfulness in daily activities
  • Restlessness or feeling "on the go"
  • Interrupting others or difficulty waiting your turn
  • Making impulsive decisions

Diagnosis of Adult ADHD

Diagnosing ADHD in adults involves a comprehensive assessment that typically includes:

  • Clinical interviews to assess current symptoms and developmental history
  • Standardized rating scales and questionnaires
  • Information from partners, family members, or close friends when possible
  • Ruling out other conditions that might explain the symptoms

At London ADHD Clinic, our assessment process is thorough and follows best practice guidelines to ensure an accurate diagnosis.

Treatment Options

Effective treatment for adult ADHD typically involves a multimodal approach that may include:

  • Medication: Stimulant and non-stimulant medications can help manage core ADHD symptoms
  • Psychotherapy: Cognitive-behavioral therapy (CBT) specifically designed for ADHD can help develop coping strategies
  • Coaching: ADHD coaching focuses on practical skills for organization, time management, and planning
  • Lifestyle modifications: Regular exercise, adequate sleep, and nutrition can support overall management

Living with ADHD

With proper diagnosis and treatment, adults with ADHD can lead fulfilling, successful lives. Many adults with ADHD have unique strengths, including creativity, problem-solving abilities, and high energy levels that can be channeled effectively with the right support.

If you suspect you may have ADHD, seeking a professional assessment is an important first step toward understanding and managing your symptoms.
