Why Elderly Patients Have Unique Neurological Needs
The ageing brain is not simply a younger brain that is slower. It has less reserve, a more delicate blood supply, and a reduced ability to buffer stress — whether that stress is an infection, dehydration, a new medicine or a night in an unfamiliar hospital ward. As a result, older people often show illness in ways that are easy to misread. A urinary infection may present not as fever but as sudden confusion. A silent stroke may show up as a change in walking rather than obvious weakness.
A second challenge is that problems overlap. An older person may have mild memory change, some neuropathy in the feet, a touch of Parkinsonism, poor vision and several medicines all at once — and it is the combination, not any single problem, that leads to a fall or to confusion. Untangling which factor is doing what requires patience and a broad view, which is exactly what geriatric neurology provides.
The most damaging assumption families and even some doctors make is that decline is simply 'old age' and nothing can be done. Often that is wrong. Many neurological problems in the elderly are treatable or reversible, and even where a condition cannot be cured, a great deal can be done to preserve safety, dignity and independence. Dr. Iqbal Singh approaches every older patient with that mindset — look carefully before concluding nothing can help.
Falls and Balance Disorders (Causes, Assessment, Prevention)
A fall in an older person is never trivial. It is one of the leading causes of injury, hip fracture, loss of independence and even death in the elderly — and once someone has fallen, fear of falling again often makes them move less, which weakens them further. Yet falls are rarely just 'being careless'; they almost always have identifiable, and often correctable, causes.
Common contributors include orthostatic hypotension (blood pressure dropping on standing, often worsened by medicines), peripheral neuropathy reducing sensation in the feet, poor vision, inner-ear (vestibular) problems like BPPV, Parkinsonism, weak leg muscles, and the sedating side effects of many drugs. Home hazards — loose rugs, poor lighting, no bathroom grab-rails, slippery floors — turn a wobble into a fall.
A proper falls assessment looks at all of these together: lying and standing blood pressure, a walking and balance examination, a review of vision and footwear, a check for neuropathy and vestibular causes, and — crucially — a careful look at the medication list. Prevention then targets what is found: adjusting drugs, treating BPPV with the Epley manoeuvre, prescribing physiotherapy for strength and balance, correcting vitamin D and vision, and making the home safer. This is high-value, practical medicine that genuinely keeps older people on their feet.
Gait Disorders in the Elderly — Including Normal Pressure Hydrocephalus
How an older person walks tells a neurologist a great deal. A shuffling, hesitant gait may point to Parkinsonism; a wide-based, unsteady gait may reflect cerebellar or sensory problems; a 'magnetic' gait, where the feet seem stuck to the floor, has its own important cause. Changes in walking are among the most common and revealing neurological signs in later life, and they deserve proper evaluation rather than being dismissed as ageing.
One gait disorder deserves special attention because it is treatable and frequently missed: normal pressure hydrocephalus (NPH). NPH is caused by a build-up of cerebrospinal fluid in the brain's cavities, and it produces a classic triad:
- Gait disturbance — a slow, shuffling, wide-based 'magnetic' walk, usually the first and most prominent sign.
- Dementia — memory and thinking slow down.
- Urinary incontinence — loss of bladder control appearing later.
The reason NPH matters so much is that it can be reversed. When it is recognised — often on an MRI scan showing enlarged ventricles — inserting a shunt to drain the excess fluid can dramatically improve walking and thinking in suitable patients. Tragically, NPH is often mislabelled as untreatable dementia and the family loses years of good life that surgery could have restored. Any older person with the triad of walking trouble, memory decline and incontinence should be assessed for NPH.
Peripheral Neuropathy in Elderly Diabetics
Peripheral neuropathy — damage to the small nerves of the hands and feet — is extremely common in older people, and in India the leading cause is diabetes. Given how many of Gini's patients live with long-standing diabetes, this is one of the most frequent neurological problems we see in the elderly.
Diabetic neuropathy usually begins in the feet, producing numbness, tingling, burning pain, or a feeling of walking on cotton wool. The numbness is deceptively dangerous: it removes the position sense that keeps a person steady, contributing to falls, and it means minor foot injuries and ulcers go unnoticed until they become serious — a major cause of foot infections and amputation in diabetics. The burning pain, meanwhile, can be severe and rob patients of sleep.
Management works on two fronts. First, tackling the cause — tight long-term blood sugar control, and correcting contributing factors like vitamin B12 deficiency (common, and easily missed, especially in older vegetarians). Second, treating the symptoms — specific nerve-pain medicines such as pregabalin, gabapentin or duloxetine can substantially ease burning pain, alongside dedicated foot care and protective footwear. Gini's neurology and endocrinology teams manage this together, because good glucose control is itself part of the neurological treatment.
Sleep Disorders in the Elderly (Insomnia, Restless Legs, REM Sleep Behaviour Disorder)
Sleep changes with age, but poor sleep in the elderly is not something to simply accept — it worsens memory, mood, balance and daytime function, and several sleep disorders have specific treatments.
Insomnia is common and often driven by fixable factors: daytime napping, caffeine, an enlarged prostate causing night-time urination, pain, anxiety, or the effects of medicines. The safest first approach is good sleep habits and treating the underlying cause, rather than long-term sleeping pills, which themselves cause confusion and falls in older people.
Restless legs syndrome (RLS) causes an irresistible urge to move the legs at rest, especially in the evening, badly disrupting sleep. It is frequently linked to iron deficiency or kidney problems, so checking iron stores is worthwhile, and effective medicines exist.
REM sleep behaviour disorder (RBD) deserves particular attention. Normally the body is paralysed during dreaming; in RBD that protection fails, so the person physically acts out their dreams — shouting, punching, kicking or leaping from bed, sometimes injuring themselves or their partner. Beyond the immediate risk, RBD is important because it can be an early marker of Parkinson's disease and related conditions, sometimes appearing years before other symptoms. Anyone acting out vivid dreams should be assessed by a neurologist, both for safety and for what it may foreshadow.
Delirium vs Dementia — A Crucial Distinction for Families
This is perhaps the single most important distinction for families to understand, because confusing the two can cost a life. Both involve confused thinking, but they are fundamentally different.
Delirium comes on suddenly — over hours to a day or two. The person is confused, their attention wanders, and their alertness fluctuates, often worse at night. They may see things that are not there or become agitated or unusually drowsy. Delirium is a medical emergency — it is almost always triggered by something treatable: an infection (a urine or chest infection is classic), dehydration, low sodium or sugar, constipation, a new medicine, pain, or being in an unfamiliar hospital environment. Found and treated, delirium usually clears.
Dementia, by contrast, develops slowly over months to years. Memory and thinking decline gradually and steadily, but alertness and attention are usually preserved until late. It does not fluctuate hour to hour the way delirium does.
The practical message for families: if a parent or grandparent becomes suddenly confused, do not assume it is dementia setting in and wait — treat it as delirium and seek medical assessment quickly, because there is often a curable cause. Equally, a person with dementia can develop delirium on top; a sudden worsening of a person with known dementia is also a red flag for an underlying infection or other treatable problem.
Polypharmacy and Neurological Side Effects
It is common for an older person to be taking eight, ten or more different tablets, prescribed over the years by several different doctors for several different problems. This is called polypharmacy, and it is one of the most under-recognised causes of neurological trouble in the elderly. Each drug may be reasonable on its own, but together they interact, accumulate, and produce side effects — and the ageing kidney and liver clear them more slowly.
Many everyday medicines have neurological side effects that are easily mistaken for a new disease. Sedatives and sleeping pills, certain older allergy and stomach medicines (with 'anticholinergic' effects), some bladder drugs, and even certain nausea and vertigo medicines can cause confusion, drowsiness, falls, or Parkinson-like stiffness and tremor. Blood-pressure medicines can drop the pressure too far on standing and cause falls. It is entirely possible for a 'new dementia' or 'new Parkinson's' to turn out to be a medication effect that lifts once the drug is stopped.
This is why a careful medication review is a core part of any geriatric neurology assessment at Gini. We ask families to bring every medicine, including supplements and anything bought over the counter, so the whole picture can be seen. Often the most powerful treatment is not adding another drug but safely removing one — a process called deprescribing — which can restore clarity, steadiness and quality of life.
When to Seek a Geriatric Neurology Assessment
Families often wonder when a change in an older relative is worth a specialist opinion rather than 'just age'. As a guide, arrange a neurology assessment if you notice any of the following:
- A fall, or repeated near-falls and unsteadiness — even one fall deserves a look at why.
- A change in the way they walk — shuffling, freezing, veering, or a magnetic gait.
- Gradual memory or thinking decline that is affecting daily life, especially with new incontinence and walking trouble (think NPH).
- Sudden confusion — treat this urgently as possible delirium.
- New tremor, stiffness or slowness, or acting out dreams at night.
- Numbness, tingling or burning in the feet, particularly in a diabetic.
- Any sudden weakness, facial droop or speech difficulty — this is a stroke emergency; call +91 82888 43800 at once.
A geriatric neurology assessment with Dr. Iqbal Singh at Gini Advanced Care Hospital, Mohali, brings all these threads together — examining the patient, reviewing every medicine, and looking specifically for the reversible causes that are so often missed. Bringing along a family member who has witnessed the changes makes the assessment far more accurate. To book, call 0172 4120100 or WhatsApp +91 82889 44490.
