In addition, abnormalities of key structures within the cerebello-thalamic-cortico-cerebellar loop were unveiled in some other ERMDs, despite lack of evidence of functional connectivity. Degeneration of cerebellar and thalamic regions was the pathological substrates for tremor in multiple sclerosis patients, implicated by a study based on structural MRI . Decrease in amplitude of giant cortical somatosensory-evoked potentials was confirmed in patients with DCM after alcohol ingestion , indicating the possible role of the cerebral cortex. Further studies based on neuroimaging and electrophysiology are needed to elucidate the connection between these regions.
It is the sodium salt form of γ-hydroxybutyric acid , a structural analog of GABA that interacts with GABAB receptors. When ingested orally, it could be quickly absorbed and cross the blood–brain barrier, converted into GHB within the brain . It is proved to be an agonist of most GABAB receptors as well , which also suggests that it might deliver a similar effect to ethanol. Ethanol is able to antagonize the effect of harmaline through impairment of NMDA-mediated glutamate transmission . Downregulation of EAAT2 and AMPAR among chronic alcohol assumption also suggests their possible role for ethanol responsiveness , but more studies are in need for confirm their functions.
Additional Medications
Theophylline has been used by some practitioners to treat ET, though it may also induce tremor. Propranolol and primidone only have tremor-reducing effects on about half of ET patients, and the effects are moderate. The underlying cause of essential tremor is not clear, but many cases seem to be familial.
Alcohol is a central nervous system depressant, and as such, reduces brain activity and energy levels. But when someone drinks large amounts of alcohol routinely, his or her body becomes accustomed to the continuous presence of alcohol. Deep brain stimulation has demonstrated tremor improvements of up to 85% for at least six years. Essential tremor is highly individual, and it might take some time to find the right medication or combination of medications that works for you. Essential tremor is characterised by involuntary, rhythmic shaking that is more pronounced when the individual is more active. This is called ‘kinetic tremor’ because the person experiences the tremor while performing any movement.

Alcoholic tremor was never severe, and functional disability occurred in only 17% of patients. There was no relation to age or duration of drinking, and only 1% of the alcoholics had a family history of tremor compared alcohol and essential tremor with 46% in essential tremor. Tremor frequency was significantly greater in the alcoholics than in essential tremor. Propranolol therapy decreased tremor more in the alcoholics than in essential tremor.
- There are prescribed medications that can help ease the symptoms of alcohol withdrawal, including tremors.
- If the tremor is mild and more of a nuisance than it is disabling, a benzodiazepine is considered.
- For those individuals with a mild tremor, it may be sufficient to take medication when symptoms worsen — for example, in high-stress situations.
- Postsynaptic GABAARs are first considered as a candidate participant in the pathogenesis of essential tremor .
- Tremors are involuntary movements of a part or parts of the body that occur because of alternating contraction and relaxation of muscles.
- Based on these findings, a disturbance in the Guillain–Mollaret triangle may underlie tremor pathogenesis in ET.
This suggests that the alcohol group of ethanol is not the element that provides antitremor activity and that the antitremor effect of ethanol is not due to sedation. However, clinical trials indicate a fairly substantial dropout rate of 40% because of adverse effects such as cognitive difficulty and somnolence. Alcohol addiction can lead to a number of devastating health and social problems. Individuals who suffer from alcoholism are urged to undergo outpatient detox and seek treatment at our center as soon as possible before matters get even worse. Frequent and excessive alcohol use can also cause damage to the cerebellum, an area located near the top of the brain stem that controls balance, coordination and fine motor movement. In an attempt to counterbalance the sedative effects of alcohol, the brain releases more excitatory neurotransmitters than usual, which boosts nerve activity and keeps the body in a more alert state.
