I recntly discovered my brother is using Tizanidine, can this cause sleeping issues?

Yes, tizanidine can cause all the symptoms your brother is experiencing.

Visual hallucinations were observed in 3% (n=5) of patients in 2 clinical trials. Patients were aware the events were not real in most cases, and in only one case did problems persist following discontinuation. Sedation appears to be dose related in single dose studies and may in approximately 10% of cases be severe enough to interfere with daily activities. In multiple dose studies, however, the incidence of sedation peaked following one week of treatment, and remained stable thereafter.

Nervous system side effects have frequently been associated with the use of this tizanidine. Sedation, somnolence, and asthenia have been reported in up to 48% of patients. Dizziness has been reported in 16% of patients. Duskiness, hallucinations, nervousness, insomnia, and speech disorder have been reported rarely.
