MR
Mental Retardation

Mental Retardation (MR) is a developmental disability that begins in childhood and is characterized by limitations in both intelligence and adaptive skills.

Cerebral Palsy (CP) and Mental Retardation (MR) may be the result of irreversible damage to one or more concerned areas of brain during intrauterine life, labor or infancy. A particularly vulnerable part is the Internal Capsule region of brain where most nerve fibers from the muscle controlling areas of brain come together to then pass down to the spinal cord. This area has the poorest blood supply and is the most frequent site of blood flow obstructive disorders, even in adult life.

Mental Retardation can also result from severe brain injury or infection later on.
Even Autism is now linked to discrete areas of brain damage, rather than to psycho-social causes, SPECT scan of some Autistic/Autistic spectrum children show ischemic changes in brain perfusion similar to CP.
