What are the 4 severity levels of IDD?

Mild, Moderate, Severe, Profound (F70–F73).

What is Global Developmental Delay?

Under age 5, delays in milestones, too young for reliable testing. Requires reassessment

What is Unspecified IDD?

Over age 5, can’t test properly due to impairments (blindness, deafness, etc.). Used only rarely.

Language Disorder – main features?

Problems with vocabulary, grammar/sentence structure, and discourse. Onset early, not due to other conditions

Speech Sound Disorder – main feature?

Trouble producing speech sounds → reduces intelligibility. Onset early, not due to medical/neurological issues.

Repetitions, prolongations, broken words, blocking, circumlocutions, tension, anxiety about speaking.

Social (Pragmatic) Communication Disorder – hallmark?

What are the 2 core features of Autism Spectrum Disorder (ASD)?

(1) Social communication/interaction deficits, (2) Restricted/repetitive behaviors/interests.

ASD Severity Levels?

Level 1 = support, Level 2 = substantial support, Level 3 = very substantial support

ASD specifiers?

With/without intellectual or language impairment; linked to medical/genetic condition; with catatonia.

ADHD core features?

Inattention and/or hyperactivity-impulsivity lasting ≥6 months, impairing daily life.

ADHD presentations?

Combined, Inattentive, Hyperactive/Impulsive, Partial remission.

ADHD severity levels?

Mild, Moderate, Severe.

When is "Other Specified ADHD" used?

Symptoms cause impairment but don’t meet full criteria (e.g., insufficient symptoms).

When is "Unspecified ADHD" used?

What are the core difficulties in Specific Learning Disorder (SLD)?

Specific Learning Disorder specifiers?

With impairment in reading, written expression, or math.

Specific Learning Disorder (SLD) severity levels?

Mild = compensates with support, Moderate = needs specialized teaching, Severe = ongoing intensive help.

Developmental Coordination Disorder – hallmark?

Poor motor coordination (clumsiness, slow, inaccurate). Impairs daily life.

Stereotypic Movement Disorder – hallmark?

Repetitive purposeless movements (hand flapping, head banging). May cause injury.

Severity levels of Stereotypic Movement Disorder?

Mild = distractible, Moderate = needs protective measures, Severe = continuous monitoring.

Tourette’s Disorder – criteria?

Multiple motor + ≥1 vocal tic, >1 year, onset before 18.

Persistent (Chronic) Tic Disorder – criteria?

Motor OR vocal tics (not both), >1 year, onset before 18.

Other/Unspecified Tic Disorder – when used?

Symptoms present but don’t meet full criteria for a tic disorder; either reason is stated (other) or not stated (unspecified).

Other Specified Neurodevelopmental Disorder – when used?

Symptoms impair functioning but don’t fit a specific disorder; reason given (e.g., prenatal alcohol exposure).

Unspecified Neurodevelopmental Disorder – when used?

Symptoms impair functioning but clinician doesn’t specify why criteria not met (e.g., in ER).
