AP PSYCHOLOGY

Detailed explanation-1: -If you lose too many neurons, you may develop permanent disability. The disability you experience relates to the neurons which are damaged. For example, if you lose some of the neurons in your spine, your legs could be affected, leading to problems with walking.

Detailed explanation-2: -People with brain atrophy, also called cerebral atrophy, lose brain cells (neurons), and connections between their brain cells and brain volume often decreases. This loss can lead to problems with thinking, memory and performing everyday tasks. The greater the loss, the more impairment someone has.

Detailed explanation-3: -An injury to a neuron can stop the signals transmitted to and from the brain, causing muscles to not work properly or a loss of feeling in an injured area. Nerve injuries can impact the brain, the spinal cord, and peripheral nerves.

Detailed explanation-4: -Cerebral atrophy occurs naturally in all humans. But cell loss can be accelerated by a variety of causes, including injury, infection, and medical conditions such as dementia, stroke, and Huntington’s disease. These latter cases sometimes culminate in more severe brain damage and are potentially life-threatening.
