Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Revisionist Views of Adolescent and Adult Cognition01:24

Revisionist Views of Adolescent and Adult Cognition

A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are themselves.
Cognitive Development During Adolescence01:18

Cognitive Development During Adolescence

During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the recognition that people have...
Information Processing Approach01:30

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is also...
Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists01:30

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

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. They...
Stimulants01:29

Stimulants

Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Summary
This summary is machine-generated.

Inhalant use in poly-substance users is linked to worse executive cognitive functioning (ECF) and processing speed (PS). These users also start substances younger and face more behavioral issues.

Area of Science:

  • Neuroscience
  • Psychology
  • Addiction Research

Background:

  • Investigates the cognitive impact of inhalant use among 754 poly-substance users.
  • Compares neuropsychological test scores of inhalant users (PSI) and non-inhalant users (PSO).
  • Participant demographic: 72% Hispanic American, 28% European, African, and Asian Americans.

Purpose of the Study:

  • To examine the association between inhalant use and executive cognitive functioning (ECF).
  • To assess the relationship between inhalant use and processing speed (PS).
  • To compare cognitive and behavioral outcomes in inhalant-using poly-substance users versus non-users.

Main Methods:

  • Utilized standardized neuropsychological tests to evaluate ECF and PS.
  • Employed standardized surveys for drug use severity and associated psychosocial problems.
  • Employed Multiple Analysis of Covariance (MANCOVA) for statistical comparison.

Main Results:

  • Poly-substance users who used inhalants (PSI) demonstrated significantly poorer performance on ECF and PS measures compared to non-inhalant users (PSO).
  • PSI users were younger, reported higher overall drug use, and had more psychiatric admissions than PSO users.
  • Inhalant use was associated with deficits in cognitive functions and increased behavioral problems.

Conclusions:

  • Inhalant-using poly-substance users (PSI) initiate substance use at an earlier age.
  • PSI users exhibit greater deficits in ECF and PS, alongside more behavioral problems compared to PSO users.
  • Processing speed (PS) appears to directly influence ECF and psychosocial outcomes in inhalant-using poly-substance users.
