Primary lateral sclerosis

From WikiMD's Wellnesspedia

Primary lateral sclerosis (PLS) is a type of motor neuron disease that causes muscle weakness and stiffness. It is a rare disorder that affects the nervous system, specifically the motor neurons that control voluntary muscle movement.

Symptoms[edit | edit source]

The symptoms of PLS typically begin in the legs, but can also start in the tongue or the hands. They include:

Causes[edit | edit source]

The exact cause of PLS is unknown. It is thought to be related to a breakdown in the nerve cells in the brain that control muscle movement.

Diagnosis[edit | edit source]

Diagnosis of PLS can be challenging, as its symptoms are similar to those of other motor neuron diseases, such as amyotrophic lateral sclerosis (ALS). However, PLS progresses more slowly than ALS and does not affect life expectancy. Diagnosis is typically based on a thorough clinical examination and may be supported by electromyography and magnetic resonance imaging (MRI) tests.

Treatment[edit | edit source]

There is currently no cure for PLS. Treatment is focused on managing symptoms and improving quality of life. This may include physical therapy, occupational therapy, and medications to manage muscle stiffness and other symptoms.
