Dr. Chris Kalafatis

Dr Chris Kalafatis (GMC Number: 6073739)is a Consultant Psychiatrist in London specialising in Adult ADHD, Complex ADHD, Brain Health, and neurodegenerative disorders, with particular expertise in older adults (50+) and high functioning individuals with high level of masking. A founding member of Eton Psychiatrists, he has played a pivotal role in establishing the clinic’s reputation for consultant-led clinical excellence, diagnostic rigour, and compassionate patient care.
He holds a substantive NHS Consultant Psychiatrist post at South London and Maudsley (SLaM) NHS Foundation Trust, one of Europe’s most prestigious mental health institutions, and is an Affiliate of King’s College London, where he leads research in Translational and Cognitive Psychiatry. His clinical and academic work places him at the forefront of modern psychiatric practice, particularly at the intersection of ADHD, brain health, and cognitive change across the lifespan.

Specialist Adult ADHD & Complex Presentations
Dr Kalafatis is widely recognised for his expertise in managing complex adult ADHD cases that require high-level psychiatric oversight. His practice is specifically tailored for adults whose ADHD is complicated by cardiovascular conditions, anxiety disorders, longstanding medical histories, or cognitive concerns—cases often considered too complex for standard ADHD pathways.
He has a specialist interest in ADHD in older adults (50+), recognising that ADHD does not disappear with age but often presents differently later in life. Symptoms may overlap with or mimic brain fog, memory difficulties, or early cognitive decline, leading to years of misdiagnosis or dismissal. Dr Kalafatis is highly skilled in disentangling these presentations, offering clarity to individuals who have lived for decades without answers.
By integrating brain health principles into ADHD care, he ensures that treatment plans support long-term cognitive function, alongside meaningful improvement in attention, emotional regulation, and quality of life.
Areas of specialist expertise include:
Adult ADHD assessment and treatment

Complex ADHD with medical or psychiatric comorbidities

ADHD in older adults

Brain health, cognitive change, and neurodegenerative disorders

Second opinions and diagnostic clarification

In-Person & Virtual Psychiatric Assessments
Dr Kalafatis offers flexible, accessible specialist care, providing in-person consultations in London as well as comprehensive virtual ADHD and psychiatric assessments for patients across the UK and internationally. As an early pioneer of telepsychiatry, he ensures that clinical standards remain exceptionally high, regardless of whether care is delivered face-to-face or online.

Innovation in Brain Health & Digital Psychiatry
A recognised innovator in mental healthcare, Dr Kalafatis developed the first virtual NHS Brain Health Clinic, a groundbreaking service utilising AI-driven digital cognitive assessments to support early diagnosis and intervention. This work was shortlisted for the Royal College of Psychiatrists National Awards for Research and Quality Improvement (2025).
He is also actively involved in pharmaceutical trials for dementia and brain health, ensuring his clinical practice remains informed by the latest advances in neuroscience, psychopharmacology, and cognitive medicine.

A Reputation Built on Trust and Validation
Dr Kalafatis is widely sought after for his independent, validated reputation and is frequently approached by patients seeking a specialist second opinion after feeling that their concerns have been minimised or dismissed elsewhere. Patients consistently describe him as thorough, empathetic, and deeply attentive, valuing his ability to listen carefully and provide nuanced, evidence-based explanations.
Many adults—particularly high-functioning professionals and late-diagnosed individuals—report a profound sense of relief after finally receiving clarity and validation regarding their lifelong difficulties.
