Dehydration Affects Brain Function

Symptoms of dehydration may mask themselves as signs of Dementia OR make Dementia symptoms worse.
5 key points on Hydration (Water & the Brain)
- Fluid balance is the balance of the input and output of fluids in the body to allow metabolic processes to function.
- To assess fluid balance, nurses need to know about fluid compartments in the body and how fluid moves between these compartments.
- Dehydration is defined as a 1% or greater loss of body mass as a result of fluid loss.
Symptoms include impaired cognitive function, headaches, fatigue and dry skin.
Severe dehydration can lead to hypovolaemic shock, organ failure and death. - The three elements to assessing fluid balance and hydration status are: clinical assessment, body weight and urine output; review of fluid balance charts; and review of blood chemistry.
- Fluid balance recording is often inadequate or inaccurate often because of staff shortages, lack of training or lack of time.
