Usually beginning in one or both hands,<unk>  is characterized by weakness, muscle atrophy, cramping, and often profuse fasciculations (muscle twitching). The symptoms are progressive over long periods, often in a stepwise fashion, but unlike ALS are often treatable. Sensory nerves are usually unaffected. Wrist drop and foot drop (leading to trips and falls) are common symptoms. Other effects can include gradual loss of finger extension, leading to a clawlike appearance. Cold & hot temperatures exacerbate<unk>  symptoms to such an extent, unlike other neuropathies, that this temperature response is being investigated as a diagnostic tool.
