Early Alzheimer's disease

Alzheimer’s disease is a complex condition that can affect people in different ways. The earliest symptom of Alzheimer’s disease is usually short term memory loss. Later symptoms can typically include difficulty with planning and problem solving, and sometimes problems with low mood.1

The connections in the brain, called synapses, are continuously re-formed throughout life. This means that existing synapses are replaced every 3-6 months with new ones. In a healthy brain the amount of new synapses that are formed matches the amount that are lost.

In early Alzheimer’s disease however, the loss of synapses becomes accelerated. It is not yet understood why this is the case, however research suggests that synaptic loss occurs very early in the disease progression. The loss of synapses is one of the key features of early Alzheimer’s disease.

There are an estimated 850,000 people with dementia in the UK1

Finding the missing nutrients

People living with early Alzheimer’s disease have been shown to have relatively low levels of certain nutrients in their bodies, despite eating a normal diet2,3,4,5,6,7. These nutrients are important for making new synapses. Omega 3 fatty acids, uridine monophosphate and choline, together with several key vitamins, all work together to help this process. 

Research suggests that taking a carefully formulated oral nutritional supplement may be beneficial where the levels of vitamins, omega-3-fatty acids, and the other nutrients (including uridine monophosphate and choline) are above those that can be achieved in a normal diet.
