A seizure is a sudden change in behavior, movement or consciousness due to abnormal electrical activity in the brain. [3] [6] Seizures can look different in different people. It can be uncontrolled shaking of the whole body (tonic-clonic seizures) or a person spacing out for a few seconds (absence seizures).
Of these, 3% to 5% develop DTs or have seizures. [2] The name delirium tremens was first used in 1813; however, the symptoms were well described since the 1700s. [7] The word "delirium" is Latin for "going off the furrow," a plowing metaphor for disordered thinking. [4] It is also called the shaking frenzy and Saunders-Sutton syndrome. [4]
Withdrawal seizures: seizures occur within 48 hours of alcohol cessation and occur either as a single generalized tonic-clonic seizure or as a brief episode of multiple seizures. [14] Delirium tremens: hyperadrenergic state, disorientation, tremors, diaphoresis, impaired attention/consciousness, and visual and auditory hallucinations. [12]
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]
Tonic seizures produce constant contractions of the muscles. A person often turns blue as breathing is stopped. In clonic seizures there is shaking of the limbs in unison. After the shaking has stopped it may take 10–30 minutes for the person to return to normal; this period is called the "postictal state" or "postictal phase."
Earlier age of seizure onset is correlated with a higher risk of cognitive impairment. Progressive myoclonus epilepsy (PME) is a group of diseases characterized by myoclonus, epileptic seizures, tonic–clonic seizures, and other serious symptoms such as trouble walking or speaking. These rare disorders often get worse over time and can be fatal.
Temporal lobe epilepsy is the most common focal onset epilepsy, and 80% of temporal lobe epilepsy is mesial (medial) temporal lobe epilepsy, temporal lobe epilepsy arising from the inner part of the temporal lobe that may involve the hippocampus, parahippocampal gyrus or amygdala.
A tremor is an involuntary, [1] somewhat rhythmic muscle contraction and relaxation involving oscillations or twitching movements of one or more body parts. It is the most common of all involuntary movements and can affect the hands, arms, eyes, face, head, vocal folds, trunk, and legs.
