Madras Motor Neuron Disease

Madras Motor Neuron Disease (MMND) is a rare neurological disorder that affects the motor neurons in the brain and spinal cord. It is named after the city of Madras (now Chennai), India, where it was first identified.

Pronunciation

Madras: /məˈdrɑːs/ Motor Neuron Disease: /ˈmoʊtər ˈnʊərɒn dɪˈziːz/

Etymology

The term "Madras Motor Neuron Disease" is derived from the city of Madras (now Chennai), where the disease was first identified in the 1970s. The term "motor neuron disease" refers to a group of neurological disorders that selectively affect motor neurons, the cells that control voluntary muscle activity.

Symptoms

The symptoms of MMND typically begin in childhood or early adulthood and may include muscle weakness, muscle atrophy, spasticity, and sensorineural hearing loss. The disease progresses slowly and can lead to severe disability.

Diagnosis

Diagnosis of MMND is based on clinical examination, electromyography (EMG), and nerve conduction studies (NCS). Genetic testing may also be performed to rule out other similar conditions.

Treatment

There is currently no cure for MMND. Treatment is supportive and may include physical therapy, occupational therapy, and management of symptoms.
