Question

Three manifestations of Friedreich ataxia:

a) Scoliosis, cardiomyopathy, and optic neuritis
b) Progressive gait and limb ataxia, dysarthria, and loss of deep tendon reflexes
c) Progressive hearing loss, tremors, and cognitive impairment
d) Peripheral neuropathy, seizures, and dementia

Answer 1

Friedreich ataxia is a neurodegenerative disorder that primarily manifests as progressive gait and limb ataxia, dysarthria, and loss of deep tendon reflexes. Other symptoms such as scoliosis, cardiomyopathy, and optic neuritis may also be present but are not as common.

Step-by-step explanation:

Friedreich ataxia is a neurodegenerative disorder characterized by progressive gait and limb ataxia, dysarthria, and loss of deep tendon reflexes. These symptoms are primarily caused by a dysfunction in the cerebellum, the part of the brain that controls movement coordination. Other symptoms may include scoliosis, cardiomyopathy, and optic neuritis, but these are not as commonly seen as the primary manifestations.
