Asterixis (more colloquially referred to as flapping tremor) is not actually a tremor, but rather a negative myoclonus.This movement disorder is characterized by an inability to maintain a position, which is demonstrated by jerking movements of the outstretched hands when bent upward at the wrist (which can be similar to a bird flapping its wings, hence the name "flapping tremor").
Cerebellar tremor (also known as intention tremor) is a slow, broad tremor of the extremities that occurs at the end of a purposeful movement, such as trying to press a button or touching a finger to the tip of one's nose. In classic cerebellar tremor, a lesion on one side of the brain produces a tremor in that same side of the body that ...
Unusual movements including fine tremors, jerky limb movements, hand flapping and a wide-based, stiff-legged gait. Characteristic facial appearance (but not in all cases). A history of epilepsy and an abnormal EEG tracing. A happy disposition with frequent laughter
A migraine attack can be a debilitating condition. But a headache is just one part. There are other subtle warning symptoms to watch out for, neurologists say.
Tremor (usually fine shaking; tremor of the outstretched fingers). In a small study of newly diagnosed hyperthyroid patients, tremor was observed in 76% of them. [ 7 ] Some studies lay the cause for hyperthyroid tremor with a heightened beta-adrenergic state, others suggest an increased metabolism of dopamine .
Essential tremor (ET), also called benign tremor, familial tremor, and idiopathic tremor, is a medical condition characterized by involuntary rhythmic contractions and relaxations (oscillations or twitching movements) of certain muscle groups in one or more body parts of unknown cause. [6]
Tremors are symmetric about a midpoint within the movement, and both portions of the movement occur at the same speed. Unlike the other hyperkinetic movements, tremors lack both the jerking associated movements and posturing. [4] Essential tremor (ET), also known as benign essential tremor, or familial tremor, is the most common movement ...
Tremor and Other Hyperkinetic Movements is a peer-reviewed open access medical journal covering neurology with a focus on hyperkinetic movement disorders including ...
