Physiological action tremor: a basis for understanding alcohol withdrawal tremor
Currents in Alcoholism
|January 1, 1981
Summary
Ethanol intoxication can affect physiological action tremor (PAT), which shares characteristics with withdrawal tremor (WT). This study suggests PAT and WT may be regulated by identical neurophysiological mechanisms.
Area of Science:
- Neuroscience
- Physiology
- Pharmacology
Background:
- Physiological action tremor (PAT) is a common tremor observed during voluntary muscle contraction.
- Ethanol intoxication is known to affect motor control and can induce tremors.
- Withdrawal tremor (WT) is a characteristic symptom of alcohol withdrawal syndrome.
Purpose of the Study:
- To investigate the effects of ethanol intoxication on physiological action tremor (PAT).
- To compare the characteristics of PAT during ethanol intoxication with those of withdrawal tremor (WT).
- To explore the potential for shared regulatory mechanisms between PAT and WT.
Main Methods:
- Tremor measurements were recorded from 12 healthy male volunteers.
- Measurements were taken both in a baseline state and during induced ethanol intoxication.
- Analysis focused on frequency, amplitude, and electromyographic features of the tremor.
Main Results:
- Ethanol intoxication altered the characteristics of physiological action tremor (PAT).
- The observed PAT during intoxication exhibited similarities in frequency, amplitude, and EMG patterns to reported withdrawal tremor (WT) data.
- These similarities suggest a potential overlap in the underlying physiological control systems.
Conclusions:
- Physiological action tremor (PAT) is modified by ethanol intoxication.
- The findings provide evidence supporting the hypothesis that PAT and WT may be governed by common neurophysiological pathways.
- Further research is warranted to elucidate the precise mechanisms involved in the control of these tremors.

01:15Drug Abuse and Addiction: Pharmacological Phenomena
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...
01:27CNS Depressants: Alcohol and Nicotine
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...
01:28Depressants
Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.

01:24Parkinson Disease ll: Pathophysiology
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
01:12Alterations in Muscle Tone ll
Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...
01:11Alterations in Muscle Tone lll
Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
