Intellectual Disability
Early signs of Intellectual Disability to spot on a home visit
On a home visit, look for a child consistently slower than peers across several areas at once — motor milestones, babble and words, understanding instructions, play and self-help. Intellectual development disorder (ICD-11 6A00) is suspected when delay is broad and persistent, not a single skill. You don't diagnose — you spot the pattern and route promptly to a developmental check.
A frontline visit rarely begins with a diagnosis — it begins with a parent's question and a child who is reaching milestones a little later than expected. Noticing the pattern early is what turns a routine home visit into timely support.
In short
During a home visit, look for a child who is consistently slower than peers to reach developmental milestones across several areas at once — sitting, walking, babbling, words, understanding simple instructions, and everyday self-help. Intellectual development disorder (ICD-11 6A00) is suspected when delay is broad rather than in just one domain, and persists over time. You are not diagnosing — you are spotting a pattern worth referring for a developmental check.Signs to watch across the home visit
Motor & physical- Late head control, sitting, crawling or walking compared with siblings or neighbours' children
- Poor coordination or floppy/stiff muscle tone
Communication & understanding
- Late babbling, few or no words at the expected age, slow vocabulary growth
- Difficulty following simple instructions appropriate for age
Learning & play
- Struggles to learn everyday routines other children pick up easily
- Limited curiosity, problem-solving or pretend play for age
Self-help & social
- Slow to feed, dress or toilet independently when peers manage
- Difficulty understanding cause-and-effect or simple social rules
The key pattern is delay across multiple areas together, plus a persistent parental concern — both are sensitive early indicators worth acting on.
When to refer
A child does not need to meet full ICD-11 6A00 criteria to be referred. In young children the right stance is watch, monitor and route promptly to a general developmental check at your PHC or a developmental centre — never "wait and see" when delays span several areas. Refer in parallel for a hearing and vision check, as these can mimic or worsen delay.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care — your home-visit observations strengthen that pathway, they don't replace it. The AbilityScore® is a clinician-administered structured assessment that gives an objective multi-domain baseline, and early intervention therapy builds on that profile.Trusted sources

What to watch
Escalate to a prompt referral when delays span several areas together and persist, or when developmental delay coexists with loss of skills, seizures, or feeding and growth concerns — these warrant medical referral, not monitoring.
Try this at home
Quick 10-minute home check: compare the child against a same-age sibling or neighbour's child on sitting/walking, words, and following one simple instruction. Two or more areas behind, plus parental worry, is enough to refer.

Frequently asked
Can a frontline worker diagnose intellectual disability at home?
No. A home visit is for spotting patterns and referring. A diagnosis and a clinical AbilityScore® are formed only at a Pinnacle Blooms Network centre under qualified clinician care.
What single pattern matters most during a home visit?
Delay across several areas at once — motor, language, understanding, play and self-help — rather than a lag in one skill alone. Broad, persistent delay plus parental concern is the cue to refer.
Should I refer even if I'm unsure?
Yes. A child need not meet full ICD-11 6A00 criteria to be referred. Persistent parental concern is itself a sensitive indicator. Refer in parallel for a hearing and vision check.
