Caregiver Burden in Semantic Dementia with Right- and Left-Sided Predominant Cerebral Atrophy and in Behavioral-Variant Frontotemporal Dementia.

Background: Caregiver burden is a serious concern for family caregivers of dementia patients, but its nature is unclear in patients with semantic dementia (SD). This study aimed to clarify caregiver burden for right- (R > L) and left-sided (L > R) predominant SD versus behavioral-variant frontotemporal dementia (bvFTD) patients.

Methods: Using the Japanese version of the Zarit Burden Interview (ZBI) and the Neuropsychiatric Inventory, we examined caregiver burden and behavioral and psychological symptoms of dementia (BPSD) in 43 first-visit outpatient/family caregiver dyads (bvFTD, 20 dyads; SD [L > R], 13 dyads; SD [R > L], 10 dyads).

Is sense of coherence helpful in coping with caregiver burden for dementia?

Background: Sense of coherence (SOC) is associated with a reduced risk of various health problems and is thought to be a major factor related to the ability to cope with stress. In the present study, we examined the association between caregiver burden and SOC among caregivers to persons with dementia.

Methods: Participants included 274 caregivers or family members of community-dwelling elderly dementia patients.

Sleep duration and its association with sleepiness and depression in "ronin-sei" preparatory school students.

Purposes: The Japanese word "ronin-sei" refers to a student who has failed their university entrance examination and is preparing to re-take the examination in the following year. We aimed to determine how sleep duration is associated with daytime sleepiness or depression in ronin-sei because impaired daytime performance is known to result from sleep deprivation.

Methods: The participants in this cross-sectional study were 1075 ronin-sei and 285 university students.

Sense of coherence, health problems, and presenteeism in Japanese university students.

Aim: Sense of coherence (SOC) is thought to be a major determinant in maintaining health. SOC gained attention recently in the fields of psychiatry after it was reported to be associated with a lowered risk of various health problems. However, the effect of SOC as a buffer against performance impairment caused by health problems is not well known.
