what does brain shrinking mean
Know the causes. Brain atrophy is shrinking of the brain caused by the loss of its cells, called neurons. Two types of brain atrophy can occur; generalized and focal. Generalized atrophy refers to neuron loss throughout the entire brain, and focal atrophy refers to neuron loss in a specific brain region.rain atrophy is shrinking of the brain caused by the loss of its cells, called neurons.
The increase in brain size stopped with neanderthals. Since then, the average brain size has been shrinking over the past 28,000 years. The cranial capacity has decreased from around 1,550 cm 3 to around 1,440 cm 3 in males while the female cranial capacity has shrunk from around 1,500 cm 3 to around 1,240 cm 3.he size of the brain is a frequent topic of study within the fields of anatomy and evolution. Brain size is sometimes measured by weight and sometimes by volume (via MRI scans or by skull volume).
