Cerebral palsy (CP) is a complex neurological condition caused by brain damage or abnormal brain development, often before or shortly after birth, which affects movement, muscle tone, and posture. Because CP varies widely in severity and symptoms, its treatment is…
Spinal muscular atrophy (SMA) is caused primarily by genetic mutations that affect the production of a crucial protein called survival motor neuron (SMN). The key gene involved is known as SMN1. Normally, this gene provides instructions for making the SMN…
Muscular dystrophy is a group of genetic disorders characterized by progressive muscle weakness and degeneration. The way muscular dystrophy is inherited depends on the specific type of the disease, as different forms have distinct genetic causes and inheritance patterns. Understanding…
Myasthenia gravis is a condition that causes muscle weakness due to a breakdown in communication between nerves and muscles. The symptoms can vary widely but generally involve muscles becoming weak and tiring quickly, especially after use, and often improving with…
Guillain-Barré syndrome (GBS) is caused by an abnormal immune response in which the body’s immune system mistakenly attacks the peripheral nerves, the network of nerves outside the brain and spinal cord. This immune attack leads to inflammation and damage to…
Bell’s palsy is diagnosed primarily through clinical evaluation, where a healthcare provider carefully examines the patient’s facial movements and symptoms to identify characteristic signs of facial nerve paralysis.
