There are few studies addressing caregivers of bipolar disorder (BD) patients, especially patients who are older adults with an increased need for care, often given by a relative. The aim of this study was to describe which factors increase caregiver burden among caregivers of elderly BD outpatients. ⋯ In this group of elderly BD patients, caregiver burden was more associated with symptoms frequently seen in others diseases as in dementia than with depressive, manic, or anxiety symptoms, which are often used as treatment outcomes measures goals in BD. Potential treatable and modifiable factors associated with caregiver burden could be caregivers' depression, anxiety, and medical comorbidities, as well as support for caregivers in terms of services and social relationships.

Sleep problems in people with dementia are common and place a high burden on caregivers. Although hypnotic agents are often used to treat sleep disturbances, their use is associated with a considerable number of high-risk side-effects such as daytime sleepiness, amnesia, and an increased frequency of falling. The administration of bright light therapy (BLT) in the morning was a non-pharmacological remedy that was expected to treat sleep disorders in patients with dementia by entraining the circadian rhythm to ameliorate disturbances to the normal sleep-wake cycle. However, there are some unsolved issues related to the application of BLT, including the types of dementia for which it is effective and its efficacy in the different stages of cognitive decline and dementia. Furthermore, a protocol for effective BLT has not yet been proposed. ⋯ BLT could be an effective strategy for treating dementia patients, depending on their type and grade of their dementia. To confirm this hypothesis, it would be necessary to study a larger number of cases. Non-pharmacological therapies for sleep disorders should be emphasized as a safe form of treatment for patients with dementia.

Falling represents a major public health problem among older persons because it leads to premature mortality, loss of independence, and placement in assisted-living facilities. The purpose of this study was to assess the main features and risks for falls among persons older than 65 years of age as well as to quantify their fear of falling. ⋯ The frequency of falls among older people was similar to those in other populations. These results could be used to help select older persons who should be enrolled in fall prevention programmes.

Current diagnostic criteria recommend neuroimaging as a diagnostic support tool for the clinical diagnosis of dementia with Lewy bodies (DLB). Because DLB causes characteristic impairments and disabilities, such as neuroleptic hypersensitivity, which may significantly increase morbidity and mortality, its prompt and correct diagnosis is very important. The aim of this study was to evaluate the extent to which diagnostic accuracy can be increased by using different combinations of brain perfusion single-photon emission computed tomography (bp-SPECT), 123 I-metaiodobenzylguanidine myocardial scintigraphy (MIBG scintigraphy), and DAT-SPECT. Taking finances and patient burden into consideration, we compared the tests to determine priority. ⋯ In terms of stand-alone diagnostic means, priority should be placed on MIBG scintigraphy or DAT-SPECT for the diagnosis of DLB. However, our results suggest that the combination of bp-SPECT, MIBG scintigraphy, and DAT-SPECT increased the accuracy of the clinical diagnosis of DLB.

Observational Study
Observational study of quality of life of Parkinson's patients and their caregivers.
Parkinson's disease (PD) is a degenerative disorder that leads to a decrease in cognitive performance and affects patients' quality of life (QoL). The purpose of this study was to investigate the QoL of PD patients and their caregivers in relation to each patient's cognitive impairment. ⋯ Our results confirm a relationship between PD patients QoL and the perceived burden of their caregivers. Indeed, patients' cognitive impairment strictly correlated to lower QoL scores in both patients and caregivers and is a strong predictor of caregiver stress and burden. These results emphasize the importance of implementing early interventions to prevent or ameliorate caregivers' burnout.
