Motor Skills Impairment

Share:

Motor skills are motions carried out when the brain, nervous system, and muscles work in concert. The cerebellum is deeply interconnected with sensory-motor areas of the cerebral cortex. Cerebellar ataxia and motor-based neuropathy damage both contribute to the loss or impairment of motor skills.

Cerebellar ataxia affects fine motor skills, small movements like opening a jar, holding a fork, cutting your food, or using a small tool. Fine motor skills use the muscles in your fingers, hands, wrists, toes, lips, and tongue.

Motor-based neuropathy affects the gross motor skills, the large muscles in the arms, legs, torso, and feet. These skills are responsible for bigger movements like sitting, standing, walking, running, and balance.

Sources: Superficial siderosis is a rare neurologic disease characterized by progressive sensorineural hearing loss, cerebellar ataxia, pyramidal signs, and neuroimaging findings revealing hemosiderin deposits in the spinal and cranial leptomeninges and subpial layer. The disease progresses slowly, and patients may present with mild cognitive impairment, nystagmus, dysmetria, spasticity, dysdiadochokinesia, dysarthria, hyperreflexia, and Babinski signs. Additional features reported include dementia, urinary incontinence, anosmia, ageusia, and anisocoria. Superficial siderosis MedGen UID: 831707 •Concept ID: CN226971 •Finding Orphanet: ORPHA247245
