Research supports a connection between perceptual difficulties, ADHD, and some movement disorders including Tourette syndrome. Anecdotally, many families report light sensitivity and perceptual difficulties in children with tics and ADHD. It’s not unusual to hear comments like this:
- Bright stores and fluorescent lights make my child hyper.
- When my son goes outside on sunny days his tics increase and he complains it’s too bright
- My daughter likes to read with the lights low; she says this helps her reading.
- Bright lights or fluorescent lights make the text move around on the page when I’m trying to read.
