Nutrition impact symptoms and the risk of malnutrition in people with Parkinson's disease: A cross-sectional study.

BACKGROUND: People with Parkinson's disease (PD) often experience symptoms that affect their ability to eat. This may contribute to weight loss and increased risk of malnutrition. The present study aimed to quantify the extent of nutrition impact symptoms (NIS) in the population and a scoring system of NIS was incorporated in the tool used to identify malnutrition. METHODS: In this cross-sectional study, members of the Norwegian Parkinson's Association, with any PD diagnosis and stage of illness, were invited to respond to an online 24-item questionnaire. Questions from two validated questionnaires, comprising the abridged Patient-Generated Subjective Global Assessment (aPG-SGA) and the Radboud Oral Motor Inventory for Parkinson's disease (ROMP), were adapted to an online format. RESULTS: The questionnaire was sent to 3047 members, of which 508 persons (17%) responded (61% men). In total, 59% were categorised as well-nourished, 34% at risk of malnutrition and 6.5% as malnourished. One quarter of all participants reported symptoms that affected food intake. The most frequent symptoms were constipation (14.2%) and dry mouth (13.4%). Malnourished participants reported a mean ± SD of 3.4 ± 1.4 symptoms versus 0.1 ± 0.3 per well-nourished participant. Malnourished participants had more swallowing problems than well-nourished participants, with a mean ± SD total ROMP score of 15.5 ± 6.0 versus 9.0 ± 2.9 (p < 0.001). As the number of points in the ROMP score increased by one, the points in the aPG-SGA score increased with 37% (95% confidence interval = 0.309-0.428). CONCLUSIONS: Risk of malnutrition was largely related to NIS, especially dysphagia in people with PD. Symptoms affecting food intake should be systematically mapped and treated in conjunction with PD to prevent malnutrition.

Consequences of serious parental health events on child mental health and educational outcomes.

I show that serious, yet common, parental health events in childhood have immediate and lasting effects on mental health and educational outcomes for children. Following a parental health event, the children are more likely to receive therapy and consume anti-depressant (AD) medication. More so, the children achieve lower test scores and have lower school enrollment rates. The effect immediately occurs following the event and persists at least into early adulthood. I find that the effect on test scores doesn't differ significantly across family income, but that children from low-income families are more likely to be prescribed ADs following the event, while children from high-income families are more likely to receive therapy. Exploiting differences in general practitioners' behavior in prescribing AD and referring children to therapy, I find suggestive evidence that children who are more exposed to medical treatment of mental health issues have lower educational attainments in early adulthood.

Association of Malnutrition with Functional and Cognitive Trajectories in People Living with Dementia: A Five-Year Follow-Up Study.

BACKGROUND: In dementia, functional status depends on multiple factors in addition to cognition. Nutritional status is a potentially modifiable factor related to homeostasis and proper functioning of body systems and may contribute to cognitive and functional decline. OBJECTIVE: This paper aims to analyze the association of malnutrition with the course of cognitive and functional decline in people living with dementia. METHODS: This is an analysis of a longitudinal cohort study, the Dementia Study of Western Norway. Data of 202 patients diagnosed with mild dementia were analyzed; Alzheimer's disease (AD) (n = 103), Lewy body dementia (LBD) (n = 74), and other dementias (OD) (n = 25). Cognition was assessed with the Mini-Mental State Examination and functional decline through the activities of daily living included in the Rapid Disability Rating Scale. The Global Leadership Initiative on Malnutrition Index was used to determine nutritional status. Associations of nutritional status with cognitive and functional decline were evaluated through adjusted linear mixed models. RESULTS: At baseline, the prevalence of general malnutrition was 28.7%; 17.3% were classified as moderate malnutrition and 11.38% as severe malnutrition (there were no significant differences between AD and LBD). Malnutrition at diagnosis and over follow-up was a significant predictor of functional-decline, but not of cognitive decline. CONCLUSION: According to our results malnutrition was associated with faster functional loss but, not cognitive decline in older adults with dementia. A more comprehensive dementia approach including nutritional assessments could improve prognosis.
