Neurodiversity Overview

Research on the brain-behavior relationship is advancing rapidly. The resources below highlight how different conditions can influence cognitive functioning and point toward strategies that foster resilience.

ADHD in Adulthood

Attention-deficit/hyperactivity disorder in adults often presents with inattention, impulsivity, and difficulty organizing or completing tasks.

Neurodegenerative Conditions

Alzheimer’s disease, Lewy body dementia, cerebrovascular disease, and frontotemporal degeneration affect thinking in distinct patterns.

Mood Factors and Cognition

Depression and anxiety influence attention, processing speed, and memory, sometimes mimicking neurodegenerative syndromes.

Brain Plasticity and Recovery

Neuroplasticity is the brain’s ability to rewire after stroke, injury, or illness, supporting recovery of thinking and daily skills.

Stroke Awareness

A stroke disrupts blood flow to the brain; rapid recognition saves brain tissue and supports better rehabilitation outcomes.

Anxiety and Cognition

Anxiety biases perception toward threat, reducing working-memory capacity and flexible thinking.

Traumatic Brain Injury

Concussion and more severe TBIs can trigger changes in attention, processing speed, mood, and sensory tolerance.

Autism Spectrum in Adulthood

Autistic adults often navigate sensory sensitivities, social fatigue, and executive-function differences that impact daily life.
