The Mental Capacity Act provides a statutory framework to empower and protect people (generally aged 16 or over) who may lack capacity to make some decisions for themselves. This could include people with:
- dementia
 - learning disabilities
 - mental health problems
 - stroke
 - head injuries
 
Lack of capacity may also be because at the time the decision needs to be made, they are:
- unconscious or barely conscious (due to an accident or being under anaesthetic)
 - the influence of alcohol or drugs affects their ability to make a decision
 
The act makes it clear who can take decisions, in which situations, and how they should go about this. It enables people to plan ahead for a time when they may lack capacity.
The act covers major decisions about:
- property and affairs
 - healthcare treatment
 - where the person lives
 - everyday decisions about personal care
 
The (GOV.UK) includes:
- a summary with key information about the act
 - some of the changes that have happened due to it coming into effect
 - the code of practice which provides guidance on how the act works on a day-to-day basis
 - case studies
