Experts have found that there are no failsafe drugs to treat dementia and stated that doctors just need to try and find one which helps there patient.
Guidelines from the American Academy of Family Physicians said that a hit-or-miss approach to prescribing medication is the only way to assess which drug is most effective for an individual.
These statements were made after the group reviewed the results of 96 studies of five different dementia drugs – looking for any effect the medications may have upon cognition, global function, behaviour, mood and quality of life
Dr Amir Qaseem of the American College of Physicians, who led the study, said that none of the medications worked for people in general although some patients did see benefits.
Dementia currently affects 700,000 people living in the UK, according to statistics from the Alzheimer's Society.
This number is set to rise to over one million by 2025.
