However, several studies indicated that metabolic and nutritional dysfunctions have a relevant influence on disease outcome. The confluence of several disturbances, including disruption in fat and glucose metabolism, with nutritional component abnormalities, could be a crucial event when associated with dopamine depletion in the striatum of patients with PD. It was discussed that there may be a relationship between decreased insulin resistance and cholesterol lower levels as a possible risk factor to dementia associated with PD (PDD). The possibility that nutritional habits, metabolic disturbances, and dopamine depletion in the striatum could have a synergic action on PDD is taken into consideration. Thus, future studies should establish dietary measures for elderly patients with PD, associated or not with dementia.555-568engBody compositionFat metabolismGlucoseParkinson’s dementia dietParkinson’s diseaseParkinson’s nutritionCapítulo de livro10.1016/B978-0-12-815950-7.00035-72-s2.0-85147600787
