Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

1.3K
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....

Alzheimer's Disease: Overview

2.0K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Alzheimer's Disease: Treatment

1.2K
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Modeling in Therapy01:26

Modeling in Therapy

695
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
Participant Modeling
Participant modeling involves therapists demonstrating calm and effective behaviors in...

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

1.7K
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Area of Science:

  • Neuroscience
  • Animal Models
  • Behavioral Science

Background:

  • Attention deficit hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder.
  • Current ADHD models often lack comprehensive feature replication.
  • Epidemiological studies suggest a link between antecedent ADHD symptoms and dementia.

Purpose of the Study:

  • To establish the first invertebrate model of ADHD.
  • To validate the model's ability to reproduce core ADHD features.
  • To explore potential insights into ADHD pathogenesis and treatment.

Main Methods:

  • Development of a novel invertebrate model.
  • Assessment of hyperactivity and behavioral responses.
  • Evaluation of dietary and pharmacological interventions (simple carbohydrates, dextroamphetamine).

Main Results:

  • The invertebrate model successfully replicated major ADHD features.
  • Hyperactivity was exacerbated by simple carbohydrates.
  • A reversible response to dextroamphetamine, including a paradoxical effect, was observed.
  • Male predominance in ADHD-like behaviors was noted.

Conclusions:

  • This invertebrate model provides a novel platform for ADHD research.
  • Findings may illuminate ADHD pathogenesis and inform treatment strategies.
  • The model's relevance is enhanced by potential links to neurodegenerative conditions like dementia.
