Cerebellar hypoplasia (CH) is a neurological condition in which the cerebellum is smaller than usual or not completely developed.
[2] The cerebellum is the brain's main control center for planning, adjusting, and executing movements of the body, the limbs and the eyes.
For humans, current theories support that what the cerebellum does to sensorimotor and vestibular control, it also does to cognition, emotion, and autonomic function.
[7] Development of the cerebellum starts in a fetus in utero and, depending on the species, may continue for some period after birth.
[14] Other possible causes, if they occurred during the development period of the cerebellum and inhibit its growth, include:[15] Numerous problems can be mistaken for CH.
These include (but are not limited to): In 2004, a study was published that linked ketamine to post-anesthetic cerebellar dysfunction in cats.
