Paralysis

Paralysis is partial or complete loss of muscle function. It can affect a specific muscle, one side of the body, both legs, or all four limbs — depending on where the nerve or brain problem is. Stroke is the commonest cause of sudden paralysis in India; spinal cord injury, nerve damage, and infections are other major causes.

Red flags — dial 112

• Sudden weakness on one side with facial droop, slurred speech, arm drift — stroke (FAST).
• Sudden weakness with neck or back injury — don't move the person unless absolutely necessary.
• Ascending weakness (legs then trunk then breathing) — Guillain-Barré syndrome.
• Weakness with fever, rash, stiff neck — meningitis/encephalitis.
• Severe weakness + bladder/bowel changes — spinal cord compression.

Common causes

• Stroke — sudden; most often one-sided.
• Spinal cord injury — accidents, falls, spinal TB, tumour, abscess.
• Guillain-Barré syndrome — post-infection autoimmune; progressive over days.
• Nerve injuries — pressure, trauma; specific muscle groups.
• Bell's palsy — sudden one-sided facial weakness (see Bell's Palsy page).
• Brain infections, tumours, multiple sclerosis, motor neuron disease.
• Diabetic nerve disease, B12 deficiency, severe electrolyte disturbance.

What matters in India

• Don't attempt "home remedies" for acute one-sided weakness — herbal drops, pressure on the eye, finger pressure kits delay stroke treatment and cause preventable long-term disability.
• Stroke time window is a few hours — dial 112 and get to a stroke-ready hospital.
• Rehabilitation matters — physiotherapy, occupational therapy, speech therapy dramatically affect recovery; available at most Indian medical colleges and an increasing number of private centres.
• Assistive devices — through ALIMCO, ADIP, disability-certificate pathway.
• Support networks — India has several stroke and SCI support organisations; disability schemes apply.

Recovery

Most recovery after stroke and many other causes happens in the first 3-6 months with consistent rehabilitation — but gains continue for much longer. Prevention of secondary complications (contractures, pressure sores, chest infections, blood clots, depression) is central. Don't give up early — many people make substantial progress with sustained effort.
