Introduction[edit | edit source]
Informed consent consists of two sections: information paper and consent certificate. In order to give informed consent, a person must have the ability to fully understand the research objectives or treatment through the information provided, and have the power of free choice that allows to consent or decline voluntarily.
Getting informed consent from people with dementia depends on their mental capacity. Dementia symptoms like difficulties with concentration and understanding, problems in short term memory, makes their ability to give informed consent questionable. These symptoms become more of a problem as the disease progresses. It would be appropriate to involve relatives if a person with dementia does not have the capacity to consent. However, it is necessary to understand that having dementia does not mean undoubtedly a person lacks the capacity to consent. Therefore, it is important to conduct a mental capacity assessment for people with dementia.
The Mental Capacity Act[edit | edit source]
The enactment of the Mental Capacity Act (MCA) in 2010 provides a statutory framework for assessing decision-making capacity. During the evaluation of a patient who may lack mental capacity, one must apply the following five statutory principles of the MCA:(4)
- A person must be assumed to have capacity unless it is established that he lacks capacity.
- A person is not to be treated as unable to make a decision unless all practicable steps to help him to do so have been taken without success.
- A person is not to be treated as unable to make a decision merely because he makes an unwise decision.
- An act done, or a decision made, under this Act for or on behalf of a person who lacks capacity must be done, or made, in his best interests.
- Before the act is done, or the decision is made, regard must be had to whether the purpose for which it is needed can be as effectively achieved in a way that is less restrictive of the person’s rights and freedom of action.
