Hemispatial Neglect When Half Your World Disappears

Hemispatial neglect is a neurological condition where individuals fail to notice one side of their world, often due to brain damage like a stroke. This condition affects daily activities and memory, as patients may ignore one side of their body or surroundings. Clinical tests, such as drawing a clock, help diagnose it. Despite appearing to ignore one side, the brain still processes some information from it. Damage to the right parietal lobe often causes neglect of the left side, as the right lobe manages spatial awareness for both sides. The condition also links attention and alertness, with parallels seen in sleep patterns. Understanding hemispatial neglect offers insights into brain function and attention management.
