To investigate whether seizure lateralization affects sleep macrostructure in patients with left and right temporal lobe epilepsy (TLE), as rapid eye movement (REM) sleep is shorter in patients with right hemispheric cerebral infarction than with left. We retrospectively analyzed data from 16 patients with TLE (6 men and 10 women aged 34.9 ± 11.4 years) who underwent polysomnography as well as long-term video electroencephalography. Ten patients were diagnosed with left TLE and six patients with right TLE. Sleep stages and respiratory events were scored based on the American Academy of Sleep Medicine criteria. Sleep and respiratory parameters were compared between the patient groups. Percentage of REM stage sleep was significantly (p < 0.05) lower in patients with left TLE (median 8.8 %, interquartile range 5.5–13.8 %) than in patients with right TLE (median 17.0 %, interquartile range 14.1–18.3 %). The other parameters showed no significant differences. Shorter REM sleep in patients with left TLE sharply contrasts with the previous report of shorter REM sleep in patients with right cerebral infarction. Laterality of the irritative epileptic focus versus destructive lesion may have different effects on the sleep macrostructures.
