Sporadic, which is the most common form of the disease in the U. Men are affected more often than women. A-myo-trophic comes from the Greek language.
Recent years have brought a wealth of new scientific understanding regarding the physiology of this disease. Familial ALS means the disease is inherited. The senses of sight, smell, touch, hearing, and taste remain intact as well. ALS, sometimes called Lou Gehrig's disease, is a progressive brain disease that attacks the nerve cells that control muscles (motor neurons). French neurologist Jean-Martin Charcot discovered the disease in 6869. How would you like a stronger immune system or better sleep? The average lifespan of the individual after diagnosis has been reported to be 7 to 5 years. It results in the gradual degeneration and death of motor neurons that are located in the brain, brainstem, and spinal cord. The motor nerves that are affected when you have ALS are the motor neurons that provide voluntary movements and muscle control. Brigance and Tim Shaw. Myo refers to muscle, and Trophic means nourishment No muscle nourishment. ALS is progressive, meaning that the symptoms gradually worsen over time. , accounts for 95 to 95 percent of all cases.

Discover common skin conditions like psoriasis, rashes, and more in the collection of medical photos. The progressive degeneration of the motor neurons in ALS eventually leads to their demise. In those families, there is a 55% chance each offspring will inherit the gene mutation and may develop the disease.
