RESUMO
BACKGROUND: Motor and cognitive deficits and consequently mobility problems are common in geriatric patients. The currently available methods for diagnosis and for the evaluation of treatment in this vulnerable cohort are limited. The aims of the ComOn (COgnitive and Motor interactions in the Older populatioN) study are (i) to define quantitative markers with clinical relevance for motor and cognitive deficits, (ii) to investigate the interaction between both motor and cognitive deficits and (iii) to assess health status as well as treatment outcome of 1000 geriatric inpatients in hospitals of Kiel (Germany), Brescia (Italy), Porto (Portugal), Curitiba (Brazil) and Bochum (Germany). METHODS: This is a prospective, explorative observational multi-center study. In addition to the comprehensive geriatric assessment, quantitative measures of reduced mobility and motor and cognitive deficits are performed before and after a two week's inpatient stay. Components of the assessment are mobile technology-based assessments of gait, balance and transfer performance, neuropsychological tests, frailty, sarcopenia, autonomic dysfunction and sensation, and questionnaires to assess behavioral deficits, activities of daily living, quality of life, fear of falling and dysphagia. Structural MRI and an unsupervised 24/7 home assessment of mobility are performed in a subgroup of participants. The study will also investigate the minimal clinically relevant change of the investigated parameters. DISCUSSION: This study will help form a better understanding of symptoms and their complex interactions and treatment effects in a large geriatric cohort.

Whipple disease (WD) is a rare systemic infection caused by Tropheryma whippelii. Neurological involvement has been recognised in 40% of patients, either as initial manifestations or during the course of the disease. We report on a 45 years-old man with WD with initial, persistent and irresistible episodes of daytime somnolence. The patient was HLA-DQB1*0602 positive (genetic marker for narcolepsy). WD diagnosis was suspected on clinical and MRI basis and confirmed by histological and immunohistochemical study of duodenal biopsy. Forty months later all clinical features improved, narcoleptic-like episodes disappeared and cerebral MRI and CSF normalised. Longitudinal neurophysiological studies revealed persistent sleep pattern abnormalities with sleep fragmentation, paucity of slow wave and of REM sleep. The disruption of the hypocretin circuitry in the hypothalamic - diencephalic region triggered by the infection was the probable cause of the hypersomnia and narcopleptic symptoms. WD should be added to the list of causes of secondary hypersomnia.

A doença de Whipple (DW) é infecção sistémica rara causada pelo Tropheryma whippelii. Cerca de 40 por cento dos doentes apresentam envolvimento neurológico, seja como manifestação inicial da doença, seja durante o seu curso. Apresentamos o caso de um homem de 45 anos com doença de DW com episódios iniciais, persistentes e irresistíveis de sonolência durante a actividade diurna. O doente era positivo para o HLA-DQB1*0602 (marcador genético de narcolepsia). A suspeita do diagnóstico de DW foi levantada com base na clínica e RM e confirmada por estudo imunocitoquímico do material de biópsia jejunal. Quarenta meses mais tarde, todas as manifestações clínicas melhoraram, os episódios narcolépticos desapareceram, e a RM e o LCR normalizaram. Os estudos neurofisiológicos seriados do sono revelaram alterações persistentes caracterizadas por fragmentação do sono, escassez de ondas lentas e sono REM. A perturbação do circuito da hipocretina na região hipotálamo-diencefálica, causada pela infecção, foi a causa provável da hipersónia num doente geneticamente susceptível. A DW deve ser incluída nas causas de hipersónia secundária.
