The Clinical Features of Comorbid Pediatric Bipolar Disorder in Children with Autism Spectrum Disorder.
Autistic kids with bipolar swing in short manic bursts followed by near-normal lulls, so assess mood over time, not in one visit.
01Research in Context
What this study did
Sapmaz et al. (2018) watched kids who had both autism and bipolar disorder.
They wrote down when the children showed manic highs and calm lows.
The team wanted to see what bipolar looks like inside an ASD day-to-day picture.
What they found
The kids did not stay manic all the time.
Mood shot up in short spikes, then slid back to a quiet, almost normal baseline.
Those lulls can fool you; the child may look fine while bipolar signs are simply resting.
How this fits with other research
Chien et al. (2021) counted a whole nation and agreed: bipolar is common in ASD.
Their big numbers extend Dicle’s small picture, showing the same link happens everywhere.
Kleinert et al. (2007) earlier said "watch for mood problems"; Dicle now shows exactly what to watch.
Ghumman et al. (2026) did the same case-control trick for depression, proving the method works for mood checks in autistic youth.
Why it matters
If you only observe during the calm lull you can miss bipolar completely.
Track mood across weeks, note sudden energy bursts, decreased sleep, fast speech, then the drop-back.
Share this pattern with parents and psychiatrists so medication and behavior plans match the cycle, not the quiet day you happened to assess.

03Original abstract
The aim of this study was to describe clinical features of PBD comorbidity in children with ASD. Forty children with ASD and PBD aged 6-18 years, and 40 age- and sex-matched ASD subjects with no affective episodes were included in the study. Autism Behavior CheckList, Abberant Behavior CheckList, and Young Mania Rating Scale-Parent Version were completed. This study shows that PBD comorbidity in children with ASD involves a highly episodic course, with manic episodes, subsyndromal symptoms and interepisodic periods commonly being described in the manic symptom profile of these children. These findings need to be repeated with large samples, together with controlled studies concerning therapeutic interventions directed toward PBD comorbidity in children with ASD.
