The PCL is a simple instrument, which is both valid and reliable, for the screening of dementia in population samples of individuals with low educational level. This instrument could be useful in primary health care.

Huntington's disease (HD) is a neurodegenerative disease for which there is no curative treatment available. Given that the endocannabinoid system is involved in the pathogenesis of HD mouse models, stimulation of specific targets within this signaling system has been investigated as a promising therapeutic agent in HD. We conducted a double-blind, randomized, placebo-controlled, cross-over pilot clinical trial with Sativex(®), a botanical extract with an equimolecular combination of delta-9-tetrahydrocannabinol and cannabidiol. Both Sativex(®) and placebo were dispensed as an oral spray, to be administered up to 12 sprays/day for 12 weeks. The primary objective was safety, assessed by the absence of more severe adverse events (SAE) and no greater deterioration of motor, cognitive, behavioral and functional scales during the phase of active treatment. Secondary objectives were clinical improvement of Unified Huntington Disease Rating Scale scores. Twenty-six patients were randomized and 24 completed the trial. After ruling-out period and sequence effects, safety and tolerability were confirmed. No differences on motor (p = 0.286), cognitive (p = 0.824), behavioral (p = 1.0) and functional (p = 0.581) scores were detected during treatment with Sativex(®) as compared to placebo. No significant molecular effects were detected on the biomarker analysis. Sativex(®) is safe and well tolerated in patients with HD, with no SAE or clinical worsening. No significant symptomatic effects were detected at the prescribed dosage and for a 12-week period. Also, no significant molecular changes were observed on the biomarkers. Future study designs should consider higher doses, longer treatment periods and/or alternative cannabinoid combinations.Clincaltrals.gov identifier: NCT01502046.

ABSTRACT. Background and aims: Leganés (Spain), collected in 1993, 1995, 1997

There are considerable social and material inequalities in access to home care. In view of the poor coverage of the public system for home and personal care, these inequalities may widen in the near future. New public policy initiatives are needed to provide affordable formal family-support services.
