CNS Depressants: Alcohol and Nicotine01:27

CNS Depressants: Alcohol and Nicotine

1.5K
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...

Substance Use Disorders Affecting Sleep

536
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Negative and Cognitive Symptoms of Schizophrenia

998
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Cognitive Development During Adulthood

1.2K
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

833
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Drug Abuse and Addiction: Pharmacological Phenomena

1.5K
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...

Summary

Cognitive aging in alcohol use disorder (AUD) shows age-related changes in specific functions during abstinence, not uniform accelerated aging. Older individuals face reduced cognitive recovery odds.

Area of Science:

  • Neuroscience
  • Gerontology
  • Addiction Medicine

Background:

  • Chronic alcohol use is linked to accelerated biological and cognitive aging.
  • Cognitive aging patterns during abstinence in alcohol use disorder (AUD) are not well understood.
  • The study investigates whether cognitive aging in AUD follows accelerated aging or vulnerability models.

Purpose of the Study:

  • To examine age-related cognitive changes during abstinence in patients with AUD.
  • To assess cognitive recovery patterns in relation to age during detoxification.
  • To determine if cognitive aging in AUD aligns with accelerated aging or vulnerability hypotheses.

Main Methods:

  • 197 clinically admitted patients undergoing detoxification were assessed.
  • Neuropsychological testing was conducted at weeks two and six of admission.
  • Cross-sectional and multi-assessment data analyzed age and cognitive outcome relationships.

Main Results:

  • Age-related deviations were noted in perceptual reasoning, verbal comprehension, and short-term memory after six weeks of abstinence.
  • Older age was associated with a reduced likelihood of cognitive recovery and no cognitive impairment.
  • Each year of increased age decreased the odds of showing no cognitive impairment by 5% and recovery by 4%.

Conclusions:

  • Age-related cognitive influences in AUD are specific and not uniformly patterned.
  • Perceptual reasoning may be negatively impacted after age 60 in abstinent AUD patients.
  • Findings do not support accelerated aging or provide strong evidence for the vulnerability hypothesis.
