Delirium tremens is a component of alcohol withdrawal hypothesized to be the result of compensatory changes in response to chronic heavy alcohol use. Alcohol positively allosterically modulates the binding of GABA , enhancing its effect and resulting in inhibition of neurons projecting into the nucleus accumbens , as well as inhibiting NMDA ...
AEIOU-TIPS is a mnemonic acronym used by some medical professionals to recall the possible causes for altered mental status.Medical literature discusses its utility in determining differential diagnoses in various special populations presenting with altered mental status including infants, [1] children, [2] adolescents, [3] and the elderly.

[2] [3] To be classified as alcohol withdrawal syndrome, patients must exhibit at least two of the following symptoms: increased hand tremor, insomnia, nausea or vomiting, transient hallucinations (auditory, visual or tactile), psychomotor agitation, anxiety, generalized tonic–clonic seizures, and autonomic instability. [12]
A diagnosis of solely intention tremor can only be made if the tremor is of low frequency (below 5 Hz) and without the presence of any resting tremors. [1] Electrophysiological studies can be useful in determining frequency of the tremor, and accelerometric studies quantify tremor amplitude.
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").
Tremors can start at any age, from birth through advanced ages (senile tremor). [62] [63] Any voluntary muscle in the body may be affected, although the tremor is most commonly seen in the hands and arms and slightly less commonly in the neck (causing the person's head to shake), tongue, and legs. A resting tremor of the hands is sometimes present.
Alcohol amounting to a blood concentration of only 0.3% has been shown to reduce the amplitude of essential tremor in two-thirds of patients; for this reason it may be used as a prophylactic treatment before events during which one would be embarrassed by the tremor presenting itself. Using alcohol regularly and/or in excess to treat tremors is ...
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 ...
