10 Reasons Your Hands Might Be Shaking

9. Asterixis

Asterixis is a neurological issue that causes a loss of motor control. Experts consider the resulting tremor unique; it is characterized by irregular, involuntary jerking movements, and the exact cause remains unknown. Asterixis has links to both excessive alcohol consumption and alcohol withdrawal. Damage to the cerebellum and metabolic encephalopathies that affect brain function may also be responsible. Some people describe the motion as resembling a bird flapping its wings, giving it the common name “flapping tremor.”
