What disease causes loss of motor function?
ALS affects nerve cells in the brain and spinal cord, leading to muscle weakness, a loss of motor function, paralysis, breathing problems, and, eventually, death.
What are usually the first signs of motor neurone disease?
Early symptoms can include:
- weakness in your ankle or leg – you might trip, or find it harder to climb stairs.
- slurred speech, which may develop into difficulty swallowing some foods.
- a weak grip – you might drop things, or find it hard to open jars or do up buttons.
- muscle cramps and twitches.
What do lower motor neurons control?
Cranial nerve lower motor neurons control movements of the eyes, face and tongue, and contribute to chewing, swallowing and vocalization. Damage to the lower motor neurons can lead to flaccid paralysis, absent deep tendon reflexes and muscle atrophy.
What’s the difference between ALS and motor neuron disease?
Amyotrophic lateral sclerosis (ALS), also called classical motor neuron disease, affects both the upper and lower motor neurons. It causes rapid loss of muscle control and eventual paralysis. Many doctors use the term motor neuron disease and ALS interchangeably.
What is the main cause of motor neuron disease?
The causes of MND are unknown, but worldwide research includes studies on: exposure to viruses. exposure to certain toxins and chemicals. genetic factors.
Can you prevent motor neuron disease?
Certain dietary factors, such as higher intake of antioxidants and vitamin E, have been shown, at least in some studies, to decrease the risk of MND. Interestingly, increased physical fitness and lower body mass index (BMI) have been shown to be associated with a higher risk of MND.
How quickly do MND symptoms progress?
Progression of symptoms The symptoms of motor neurone disease begin gradually over weeks and months, usually on one side of the body initially, and get progressively worse.
