There are various ways someone can lose capacity. This could be through suffering Alzheimer’s, dementia, a stroke, brain injuries, severe post-traumatic stress disorders or severe learning disabilities. It is the Court that ultimately decides if someone lacks capacity. It is however important to recognise that capacity tests are task specific. Just because a person lacks capacity to make certain decisions i.e. in relation to their finances, they may still have capacity to make personal decisions like where to live or whether to make a Will.
