What is Adult ADHD?

ADHD is a neurological condition that affects around 5% of the population. It can affect anyone from all different walks of life.

It is important to remember that ADHD is not caused by bad parenting, diet, or social circumstances. It is something that individuals are born with, and this means that symptoms are usually noticed before the age of 13.

Due to difficulties in accessing ADHD assessments, and the unfortunate and untrue stigma’s surrounding ADHD often the diagnosis is delayed until adulthood.

What are the Symptoms of ADHD?

The symptoms of ADHD are varied and can impact on many aspects of an individuals life, whether it be education, occupation, relationships, finances or social circumstances. Common symptoms are as follows:


  • Making careless mistakes / failing to give close attention to details
  • Difficulties sustaining attention
  • Difficulties listening and with “zoning out”
  • Difficulties following through or finishing tasks
  • Difficulties in organisation and time management
  • Avoiding and procrastinating tasks
  • Losing or misplacing things
  • Forgetfulness
  • Getting distracted easily


  • Becoming highly focused for prolonged periods of time to the point you lose track of everything else going on around you. Please note this is for tasks that are particularly mentally stimulating to the individual.

Hyperactivity / Impulsivity

  • Fidgeting (playing with pens, bouncing leg, biting nails, fidgeting with hands/feet)
  • Physical restlessness
  • Mental restlessness (racing thoughts, particularly when trying to relax)
  • Difficulties relaxing
  • Difficulties with patience and waiting
  • Difficulties in social situations (being loud, interrupting, talking excessively)
  • Becoming easily bored
  • Taking risks
  • Making spur of the moment decisions

Difficulties regulating Mood

  • Mood swings
  • Irritability
  • Quick temper
  • Impatience
  • Low self-esteem
  • Inability to deal with stress

How do we diagnose Adult ADHD?

At Harley Street Mental Health we diagnose ADHD through the use of clinical interviews and the DIVA-5. This is a structured Diagnostic Interview for ADHD in adults that is internationally recognised. The interview scores symptoms for attention deficit, hyperactivity and impulsivity. These scores are mapped against the diagnostic criteria from the DSM-V. A diagnosis is made when the score is above the internationally agreed threshold. Studies have shown that this interview has a sensitivity of 90%, and a specificity of 72.9%.

At the end of the interview, if a diagnosis is made we then discuss the various treatment options, and if appropriate issue a prescription for medication.

Our Process

How do we treat ADHD?

Unfortunately there is no cure for ADHD, but it can be managed through advice and support, alongside medications.

There are a number of different medications available to treat ADHD and these will be discussed with you at the appointment.

Each individual can respond differently to medication. What may work ell for one person may not for another which is why we have titration appointments post diagnosis.

The first line medications for ADHD are known as stimulants. They boost and balance levels of neurotransmitters with the aim of improving symptoms of inattention and hyperactivity. They can be prescribed as long acting medications, or shorter acting medications. If these are not tolerated we can discuss alternative non-stimulants however these are not generally considered first line treatments.
