Nutrition plays an important role in dementia for several reasons. In summary, a balanced and nutritious diet is an important element in dementia care, as it can help preserve cognitive function, support physical health and improve the quality of life of people living with dementia.

Functioning of the brain

A nutritious diet is essential to support brain health and function. Certain nutrients, such as omega-3 fatty acids and B vitamins, have been shown to be particularly important in maintaining cognitive function and reducing the risk of dementia.

Weight and metabolism

Dementia can affect appetite and eating patterns, leading to weight loss and nutritional deficiencies. Maintaining a healthy and balanced weight is significant in supporting both physical and mental health in people with dementia.

The course of the disease

While some nutrients may have a protective effect on the progression of dementia, others may increase the risk of complications. For example, a diet containing high levels of saturated fat and sugar can increase the risk of cardiovascular disease, which in turn can negatively affect brain health.

Side effects of medicines

People with dementia may also be more likely to experience side effects from medication or other treatments, which can affect appetite and nutritional intake. It is therefore important to monitor nutritional status and adjust the diet or treatment if necessary.

Plain food and tailored diet in combination with nutritional therapy can help in early Alzheimer's disease
Achieving a well-balanced composition of essential nutrients through daily food intake can be difficult, especially in old age. For example, for older people with poor appetite, it may be recommended to try small portions and to eat more frequently. Foods for special medical purposes can support daily food intake and there are different varieties available. Support with nutrition and dietary management is best discussed with a doctor or dietician.
