Dementia Evaluation & Memory Specialist in New Delhi

Structured memory assessment that separates normal ageing from mild cognitive impairment and dementia — and rules out reversible causes first.

Medically reviewed 2026-08-29 · Dr. Sudheer Pandey, DrNB Neurology

What we offer

  • Cognitive testing with MMSE and MoCA scales
  • Screening for reversible causes: B12, thyroid, depression, medication effects
  • MRI brain to identify vascular, Alzheimer's and other patterns
  • Distinguishing Alzheimer's, vascular, Lewy body and frontotemporal dementia
  • Caregiver guidance on safety, routine and behavioural symptoms

When should memory loss be evaluated by a neurologist?

Seek evaluation when forgetfulness interferes with daily function: repeating questions within a conversation, missing medication doses, difficulty managing money or appointments, getting lost on familiar routes, word-finding trouble, or a change in personality, judgement or social behaviour. Sudden confusion over hours or days is different — that needs same-day assessment.

What happens in a dementia evaluation?

Structured cognitive testing (MMSE, MoCA) to measure memory, language, attention and executive function; blood tests screening for vitamin B12 deficiency, thyroid disease and other reversible contributors; and MRI brain to identify hippocampal atrophy, small-vessel disease, prior strokes or hydrocephalus. A history from a family member is essential — patients often under-report their own difficulties.

Which causes of memory loss are reversible?

Vitamin B12 deficiency, hypothyroidism, depression (which can closely mimic dementia), obstructive sleep apnoea, chronic alcohol use, sedative and anticholinergic medications, and normal pressure hydrocephalus. These are screened for deliberately, because treating them can partly or fully reverse the decline.

How are the types of dementia distinguished?

Alzheimer's disease typically begins with episodic memory loss. Vascular dementia often follows a stepwise course with stroke risk factors and small-vessel change on MRI. Dementia with Lewy bodies features fluctuating attention, visual hallucinations and parkinsonism. Frontotemporal dementia presents earlier with behaviour and language change rather than memory. The pattern, examination and MRI together determine the subtype.

What treatment is available?

Cholinesterase inhibitors (donepezil, rivastigmine, galantamine) and memantine are prescribed where indicated. Equally important: controlling blood pressure, diabetes and cholesterol to protect remaining brain function, reviewing and stopping medications that worsen cognition, treating depression and sleep disorders, and structured caregiver guidance on routine, safety and managing behavioural symptoms.

Frequently Asked Questions

Direct answers to common questions — when to seek care, what to expect, and what to do next.

A neurologist or a psychiatrist with cognitive-disorder experience. A neurologist is the usual choice when there are also physical signs — tremor, slowness, gait change, prior stroke — or when imaging is needed to clarify the cause.

No. Normal ageing slows recall but does not stop you managing daily life. Vitamin B12 deficiency, thyroid disease, depression, poor sleep and certain medications all cause memory problems and are treatable — which is why they are screened for first.

Structured cognitive testing such as MMSE and MoCA, blood tests including vitamin B12, thyroid function and metabolic screening, and MRI brain. Occasionally EEG or specialised testing is added when the presentation is atypical or rapidly progressive.

Most degenerative dementias cannot currently be cured, but treatment slows symptom progression, improves day-to-day function and manages behavioural symptoms. Where a reversible cause is found, correcting it can substantially improve cognition.

No — bring a family member who sees the patient daily. Their account of what has changed, and over what period, is often the single most valuable part of the assessment, since patients frequently under-report their own difficulties.

It varies by type and individual. Alzheimer's disease usually progresses gradually over years; vascular dementia can worsen in steps after further strokes. Controlling vascular risk factors and maintaining routine, activity and social engagement meaningfully affect the trajectory.
