Brain atrophy is definitely not cerebral palsy. Brain atrophy is generally caused by various reasons in adults leading to a reduction in brain volume. This is often seen in cognitive impairments or memory decline in adults. Cerebral palsy, on the other hand, is generally caused by congenital diseases or perinatal reasons, leading to damage to the central nervous system. It is a disease characterized primarily by non-progressive motor disorders. Therefore, it manifests as spastic diplegia, hemiplegia, athetosis, and symptoms of the extrapyramidal system, mainly focusing on motor disorders.
