In rare cases it can affect both sides of the face but it's most often one side caused by a single nerve. Symptoms of Bell's palsy appear suddenly and have usually peaked with 48 hours. These symptoms may include twitching, drooping in a corner of the mouth or an eyelid, and drooling.
Multiple sclerosis is an unpredictable disease with complications and symptoms that can range from minimal to devastating. The exact cause of MS is unknown but its believed to be caused by the immune system attacking myelin, the body's nerve insulator. Initial symptoms of MS are double and blurred vision, muscle weakness, and poor coordination. In the worst cases, MS causes partial and complete paralysis.
Epilepsy is a disorder that occurs when the nerves of the brain begin firing abnormally. Epilepsy is caused by an disruption in normal neuron activity. Neural activity can be disrupted by numerous things including abnormal nerve pathways in the brain, tumours, meningitis, dementia, and an imbalance of neurotransmitters or chemicals that transport signals to the nerves. This can sometimes cause odd sensations, behaviour and emotions. Convulsions, loss of consciousness, and muscle spasms are also symptoms of epilepsy.
