Hooked to doomscrolling? Neurologist Dr Sudhir Kumar shares how it affects your memory, focus and cognitive function

Neurologist Dr Sudhir Kumar of Apollo Hospitals, Hyderabad said frequent scrolling through short-form videos may reduce sustained attention over time.

Dr Kumar said short videos flood the brain with rapid, disconnected context shifts, causing heavy load on working memory and leading to mental fog or 'digital fatigue'.

Dr Kumar posted on X (formerly Twitter) on July 31 about how doomscrolling affects attention, memory, and mood based on recent cognitive and psychological research.

Excessive viewing of fast-paced videos trains the brain to anticipate constant change, making deep work and long reading sessions feel tedious.

Short-form video consumption may contribute to addiction-like behavior, causing users to spend hours on a doomscroll spiral, increasing screen exposure.
