The usual dose for seizure disorder is titrated from 100-125 mg/day up to a maintenance dose of 750-1,500 mg/day (maximum daily dosage is 2 g). [15] Open-label case series have suggested that primidone is effective in the treatment of epilepsy.
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]
For many drugs, severe toxicities in humans occur at sublethal doses, which limit their maximum dose. A higher safety-based therapeutic index is preferable instead of a lower one; an individual would have to take a much higher dose of a drug to reach the lethal threshold than the dose taken to induce the therapeutic effect of the drug.
Over-excitement of the sensorimotor cortex (cortical reflex myoclonus) or reticular formation (reticular reflex myoclonus) is also a cause of action myoclonus. Serotonin and GABA neurotransmitters are thought to cause this lack of inhibition, which is a possible explanation as to why improvements are made with the administration of serotonin ...
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 ...
Resting tremor is the most common, but kinetic tremors—occurring during voluntary movements—and postural tremor—preventing upright, stable posture—also occur. [19] Tremor largely affects the hands and feet: [ 19 ] a classic parkinsonian tremor is " pill-rolling ", a resting tremor in which the thumb and index finger make contact in a ...
New RSV vaccines are now available to help prevent serious infection in people over 60. Doctors explain the RSV vaccine and its side effects in older adults.
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 ...
