Insufficient evidence Effectiveness definitions

- Decline in memory and thinking skills in older people that is more than what is normal for their age. Taking homotaurine seems to help with very recent memory recall by a small amount in older people with a decline in memory and thinking skills.
- Parkinson disease. Taking homotaurine doesn't seem to help with most symptoms of Parkinson disease.
- A group of eye disorders that can lead to vision loss (glaucoma) .
- Hair loss.
- Other conditions.
