Conduct-Dissocial Disorder
Early signs of Conduct-Dissocial Disorder in boys
Conduct-Dissocial Disorder (ICD-11 6C91) is a repeated, persistent pattern of behaviour that violates others' rights or major age-appropriate rules, lasting months and across settings — not ordinary mischief or a strong-willed temperament. Many such behaviours signal something else (ADHD, anxiety, stress), so a clinical assessment, never a label, is the right step. Most boys with behaviour worries do not have a conduct disorder.
Every boy pushes limits — that's how childhood works. The question parents quietly carry is: when does "difficult" become a pattern worth understanding, not just managing?
In short
Conduct-Dissocial Disorder (ICD-11 6C91) is recognised when a repeated, persistent pattern of behaviour that violates the basic rights of others or major age-appropriate rules lasts well beyond ordinary mischief — typically across several months and more than one setting. It is not the same as occasional defiance, a hard week, or a strong-willed temperament. Only a qualified clinician can assess this, and most boys with behaviour worries do not have a conduct disorder.Patterns worth noticing
These signs matter when they are frequent, persistent, and across settings (home, school, with peers) — not single incidents:Aggression toward people or animals
- Frequent bullying, threatening or intimidating others
- Starting physical fights more than peers, or being deliberately cruel
Serious rule-breaking
- Running away, persistent truancy from school well before the age it's common
- Repeated lying or breaking serious rules despite clear consequences
Destruction or deceit
- Deliberately damaging property or others' belongings
- Taking things that aren't his in a repeated, deliberate way
The pattern, not the moment
- Behaviour that is markedly out of step with his age and continues over months
- Little response to usual boundaries, rewards or gentle correction
Important context: many of these behaviours can also signal something else entirely — undiagnosed ADHD, anxiety, a learning difficulty, bullying, or stress at home. That is exactly why a thoughtful assessment, not a label, is the right next step.
When to seek a check
Seek a developmental and behavioural review when worrying behaviour is persistent (several months), appears in more than one place, and is straining family life, friendships or schooling. If there is ever risk of harm to your son or others, or talk of self-harm, treat that as urgent and contact a doctor promptly. Early support is far more effective than waiting — and the earlier the understanding, the gentler the path forward.The Pinnacle way

What to watch
Watch for behaviour that is persistent over months, present in more than one setting, and out of step with his age. Treat any risk of harm to himself or others, or talk of self-harm, as urgent and contact a doctor promptly.
Try this at home
Keep a simple, calm note of when difficult behaviour happens, where, and what came just before — patterns and triggers tell a clinician far more than a list of incidents.

Frequently asked
Is my son's defiance the same as Conduct-Dissocial Disorder?
Usually not. Occasional defiance, testing limits and the odd bad week are part of normal development. Conduct-Dissocial Disorder describes a repeated, persistent pattern lasting months and across settings. Only a clinician can tell the difference after assessment.
At what age can this be assessed?
Behavioural patterns are best understood over time and in relation to a child's age. A developmental and behavioural review can begin whenever a persistent, worrying pattern is straining home, friendships or school — earlier support tends to work better than waiting.
Could the behaviour be caused by something else?
Yes, often. Similar behaviours can stem from ADHD, anxiety, a learning difficulty, bullying or stress at home. This is exactly why a careful assessment matters more than any single label.
Does noticing these signs mean my son will be diagnosed?
No. Most boys with behaviour worries do not have a conduct disorder. Noticing a pattern is simply a reason to seek a calm, professional check — not a diagnosis.
