Objective:
Primary progressive aphasia (PPA), as the language variant of frontotemporal dementia, is a neurodegenerative disease with an insidious course that has no appropriate treatment yet. The present study evaluated the effect of zolpidem on improving language function in patients with nonfluent variant PPA (nfv-PPA).
Methods:
In this interventional pilot study, patients diagnosed with nfv-PPA were evaluated for language function through the Persian Aphasia Test. Patients were then treated with zolpidem with a maximum dose of 10 mg twice daily and reevaluated after 6 weeks using the Persian Aphasia Test. Data were compared by paired samples t test. Values of P ≤ 0.05 were considered significant.
Results:
Thirteen (8 men) patients completed the study. The mean age of the patients was 58.5 ± 4.5 years. Changes were statistically significant in none of the 6 subtests including spontaneous speech content, speech fluency, auditory comprehension, sequential command comprehension, repetition, and naming.
Conclusion:
The study showed that zolpidem did not affect the improvement of language function in patients with nfv-PPA. Thus, traditional language structures do not seem to be sensitive to the modulatory effects of zolpidem. Studies with larger sample sizes will help support this hypothesis.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
