Summary
World Brain Day warnings from neurologists linked rising screen time, chronic stress and irregular sleep to cognitive decline and higher risks of stroke, dementia and mood disorders.
7-8 hours of quality sleep was the central prescription, with doctors saying sleep clears metabolic waste, consolidates memory and supports brain repair that poor rest disrupts.
Excessive evening screen use worsens the problem by suppressing melatonin and disturbing circadian rhythms, while poor sleepers often turn to phones or TV, deepening the cycle.
Indian clinicians said they are increasingly seeing memory lapses, headaches, poor concentration and mental fatigue, and urged prompt evaluation for red flags such as facial drooping, slurred speech or sudden weakness.
Doctors said many neurological harms could be reduced through regular sleep schedules, less screen exposure before bed, exercise, stress control and blood-pressure management.
