Insights

Cognitive impairment in youth with HIV is linked to functional deficits. Early screening for academic difficulties like repeating grades may identify at-risk youth needing further assessment.

Area of Science:

  • Neuroscience
  • Pediatrics
  • Infectious Diseases

Background:

  • HIV infection can lead to functional impairments.
  • Cognitive impairment is a potential consequence of HIV-associated neurological damage.
  • Understanding the link between cognitive and functional status in youth with HIV is crucial for intervention.

Purpose of the Study:

  • To investigate the association between cognitive impairment and functional impairment in youth living with HIV.
  • To determine if cognitive impairment increases the risk of functional impairment in this population.

Main Methods:

  • A cohort of 203 HIV-infected youth and 44 HIV-uninfected controls was studied.
  • Parent-reported functional impairment was assessed using measures like CBCL and VABS2.
  • A cognitive battery was administered to assess cognitive impairment, and school data (repeated grades) were collected.

Main Results:

  • A strong correlation was found between the degree of cognitive impairment and decreased function across multiple measures (CBCL, VABS2, repeated grades).
  • Cognitive impairment was associated with a significantly increased risk of functional impairment (odds ratios ranging from 1.71 to 3.47).
  • Repeating a grade was strongly associated with both cognitive impairment and functional impairment.

Conclusions:

  • Cognitive impairment is significantly associated with functional impairment in youth with HIV.
  • The presence of cognitive impairment elevates the risk for functional impairment in this cohort.
  • Screening for academic difficulties, such as repeating a grade, may serve as an effective initial step in identifying youth with HIV who require further functional assessment.

Intellectual Disability

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

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....

Disorders of the Nervous Tissue

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

Learning Disabilities01:25

Learning Disabilities

Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
