When I see a client or patient for an initial evaluation, one of the most important things I ask about is family history. I ask whether any first degree relatives (mother, father, siblings, children) and second degree relatives (aunts, uncles, grandparents, cousins) currently have, or have had mental health issues. The mental health issues I specifically ask about include:
- ADHD
- Depression
- Bipolar disorder
- Anxiety
- Panic attacks
- Substance abuse
- Alcoholism
- Attempted or committed suicide
- Schizophrenia
- Seizure disorder
- Dementia/Alzheimer's
- Any inpatient mental health treatment
Why is it so important I ask about this? Because studies have shown a majority of mental health disorders are inheritable. This means that if your parents have a certain disorder, there is an increased chance you may have that disorder as well. ADHD has a heritability rate of 75 percent. This means that if you have ADHD, there is a 75% chance that you inherited an ADHD gene or genes from at least one of your parents (Rietveld et al. 2004). Schizophrenia has a heritability rate of 64 percent, and bipolar disorder has a heritability rate of 59 percent (Lichtenstein et al. 2009).
