Defining Mental Capacity

Mental capacity refers to a person’s ability to make informed decisions about their own health, welfare and finances. It involves the ability to understand, retain, and weigh relevant information, as well as to communicate a decision.

One’s ability to make decisions is not constant and can vary depending on the specific choice and circumstances. Although we may have the capability to make routine decisions, there may be instances where we lack the capacity to make important ones. Nevertheless, this does not mean that we cannot make smaller decisions, such as choosing our daily attire.

The mental capacity of a person may be triggered by a change in behaviour or circumstances. It could also happen because of diagnosis of a condition that affects their thinking ability, or concerns about their capacity. To possess capacity, an individual must be able to comprehend and utilize relevant information in order to make choices that affect their physical and mental well-being.

Mental Capacity Assessment in Medico-legal

In the medico-legal industry, a mental capacity assessment is conducted to determine an individual’s ability to make decisions, whether small or significant, related to their daily life, health, housing, or finances. Mental capacity is an important consideration in various legal and healthcare contexts, such as when making a will, consenting to medical treatment, or managing one’s own affairs.

For individuals with traumatic brain injuries, the psychological assessment in medico legal cases helps determine if someone else needs to make decisions on their behalf. In cases of suspected dementia, the assessment is conducted to evaluate repeated irrational decisions that may cause harm. It is also common to conduct the assessment on dementia patients to assess their ability to care for themselves and on individuals with brain injuries as they approach adulthood.
