I am a consultant psychiatrist specialising in older adult’s mental health. I qualified as a doctor from Charing Cross Hospital Medical School in 1986. After further training as a physician I undertook training in psychiatry in Liverpool before a series of academic appointments at Charing Cross Hospital, Royal Free Hospital and then Imperial College London.

I have been a consultant psychiatrist at Central North West London Foundation Trust since 1998 specialising in diagnosis and treatment of dementia, depression, psychosis and other mental illnesses. My training as a physician as well as a psychiatrist enables me to provide holistic care for my patients.

I was elected as chair of the Faculty of Old Age Psychiatry at the Royal College of Psychiatrists in 2012, I am the UK representative for Old Age Psychiatry in the World Psychiatric Association and was appointed National Professional Advisor for old age psychiatry at the Care Quality Commission in 2014. I am also the Medical Director of Halcyon Doctors.

I’m specialised in various types of cognitive impairment, offering bespoke assessment, diagnosis, treatment and follow-up care. Some of the conditions I can help you with are:

• Depression
  
• Alzheimer’s disease
  
• Vascular dementia
  
• Lewy body dementia
  
• Other dementias
  
• Anxiety states including panic disorder and generalised anxiety
• Schizophrenia and other causes of psychosis

Furthermore, I have extensive experience conducting mental capacity assessments and other medico-legal work.

I welcome new private patients in London and East-Anglia and accept self-referrals, referrals from general practitioners as well as instructions from solicitors.  I would prefer to see you at your own home because it enables a more comprehensive assessment and it is often more convenient for you. Alternatively, appointments can take place in several consulting rooms across London and East-Anglia.
