Why specific care matters
Each genetic syndrome has its own risk profile. In Down syndrome, for example, aging and Alzheimer’s disease may begin earlier; in fragile X syndrome, anxiety and ADHD symptoms are common; in Prader-Willi, eating behavior and mood are concerns. Patients may find it hard to describe how they feel, so changes often show in behavior, and the assessment depends on those who live with them.
Signs that call for assessment
- Changes in behavior, irritability, aggression or withdrawal
- Loss of previously acquired skills
- Changes in sleep and appetite
- Anxiety, fears, rituals
- Sadness, apathy, crying
- Forgetfulness and disorientation
How the assessment works
The psychiatrist listens to the patient and family or caregivers, reviews developmental history and medications, and investigates medical causes of behavioral change, such as pain, thyroid problems, hearing or vision loss, constipation and infections. Clinical training and hospital experience support this investigation.
Treatment
- Treating medical causes before attributing everything to the syndrome or to psychiatry
- Medication, when indicated, with careful dosing and attention to side effects
- Guidance for family, school, workplace and therapy teams
- Follow-up through aging
When to see a psychiatrist
When changes in behavior, loss of skills, or sleep and mood changes last weeks and worry the family.
