The clinical and operative findings are reviewed in 47 patients with intractable hemifacial spasm. The syndrome was classical in its features in 45 patients and atypical in two. Mechanical compression distortion of the root exit zone of the facial nerve was noted in all 47 patients. In 46 the abnormality was vascular cross-compression, usually by an arterial loop. In one patient, a small cholesteatoma was discovered and removed. Morbidity and postoperative results are discussed.

Unawareness of deficit has been shown to affect the outcome of targeted cognitive intervention programmes applied to patients with Alzheimer' disease (AD), but the effects on multimodal therapeutic approaches have not yet been explored. This research investigated the efficacy of the Multi-Intervention Programme (MIP) approach on improving cognitive, functional, affective, and behavioural symptoms in people with mild AD. In addition, we examined whether the presence of unawareness influences the MIP outcomes. Sixty-one mild stage AD patients were randomly assigned to either an experimental group which carried out an MIP individually (48 sessions, 16 weeks duration), combining diverse cognitive tasks, training in daily life and recreational activities, or a waiting list group which did not receive any treatment for the same time period. The efficacy of MIP (vs. waiting list) was tested using various standardised neuropsychological, functional, and behavioural outcome measures. Planned analyses were carried out to determine the effect of unawareness versus awareness on such outcomes. The results showed that patients overall benefited from the MIP in terms of both cognitive and non-cognitive symptoms. AD patients with awareness of deficits showed positive effects on all outcome measures in comparison with the waiting list group, while AD patients with unawareness showed improvements in non-cognitive symptoms only. In conclusion, the presence of unawareness reduces the cognitive and functional effects of MIP in patients with mild AD.

The aim of this study was to investigate the predictors of burden for informal caregivers of patients with dementia. Based on a multidimensional approach of the optimism model proposed by Palenzuela, we assessed the moderating role of generalized expectancies of control (GEC) between caregiver stress and burden. A total of 130 patients with dementia and their main family caregivers were assessed from different rural areas of the province of Salamanca (Spain). Patients with dementia underwent a protocol to assess dementia stage, cognitive-functional impairment and behavioural symptoms. Meanwhile, the 20-item Battery of Generalized Expectancies of Control Scales of Palenzuela was completed by the family caregivers. Clinical variables of patients with dementia (progression and behavioural disorders) and GEC (success, self-efficacy, contingency, helplessness and luck) were considered as potential predictors of burden in the hierarchical regression analysis. The Zarit Burden Interview (ZBI) Scale was used as an outcome measure. The results indicated that the clinical variables could not predict burden in caregivers significantly; however, beliefs in personal abilities (self-efficacy) and internal locus of control (contingency) explained up to 32% of the variance in the ZBI scores. Family caregivers with high expectancies of self-efficacy and contingency are less vulnerable to stress. This research supports a base for interventions with informal caregivers and further study.

This paper states the role of burden in abuse of PWD, while resilience and social support are abuse protective factors. These variables should be considered in future guidelines for the prevention of abuse against PWD.
