ASD is correlated with low IQ generally but there are also more high IQ people with ASD than you'd expect, they span the whole range of intelligence. Bipolar disorder follows a J shaped distribution with IQ, having average IQ is the most protective against bipolar.
On average, People with ADHD have slightly lower IQs but they still span the whole spectrum of intelligence.
