Cognitive and Mood Changes Considerations

How can I help with decision making?

Decision-making is a challenge for the cognitively impaired. Decisions can be made that are illogical, unrealistic and harmful. To assist your loved one in the process, write out the pros and cons to make the situation more visual. Confer with a knowledgeable source such as a solicitor, doctor, neutral observer, or relative if you need to. If there are important decisions to be made, such as life planning or financial decisions, try to address these issues when cognitive decline is first noticed and before decision-making is significantly impaired. 

In December 2015, the Government passed the Assisted Decision-Making (Capacity) Act. This new Act, when commenced, will have significant implications for people who are caring for someone whose capacity to make decisions may be impaired. The Act provides a statutory framework for individuals who have impaired capacity or may have impaired capacity in the future to make legally-binding agreements to be assisted and supported in making decisions about their welfare and their property and affairs.

What is meant by altered mood states?

Altered mood states are considered neuropsychiatric rather than cognitive deficits. Neuropsychiatric changes can include mood swings, depression, irritability, anxiety, inappropriate and excessive cheerfulness (euphoria) agitation, apathy, and disinhibition.

Mood swings can fluctuate quickly between anger or rage and normal behaviour. A separate mood disorder termed pseudo-bulbar affect, also known as Involuntary Emotional Expressive Disorder (IEED), is characterised by uncontrollable episodes of laughing and/or crying, and affects 1 in 10 people with MS. These episodes are not necessarily associated with the person’s underlying emotion, and can be inappropriate to the external circumstance.

A minor stimulus, such as watching a television commercial or receiving a gift, can cause uncontrolled tears for example, while learning of a death can bring on uncontrolled laughter. Euphoria and disinhibition (inappropriate sexual talk or behaviour, loss of “social graces”) can occur in people with advanced MS. Treatment for altered mood states may involve medications, and successful management is possible. Ask a neurologist, mental health professional, or an MS nurse specialist about current treatments.

What is meant by altered levels of consciousness?

Consciousness level refers to how awake and alert a person is. Levels of consciousness include: alert, confused, drowsy, and unresponsive. Situations that might alter consciousness are medications (for example pain medications), infection, fluid and nutrition intake, or the underlying disease process. Infection, such as aspiration pneumonia, can worsen respiratory effort and affect level of consciousness.

Poor nutrition and hydration can also lead to states of altered consciousness.  Persistent vegetative state (unresponsiveness with no brain function beyond bodily activities such as heartbeat) can occur in multiple sclerosis. Care of these individuals is focused on maintaining dignity and hygiene. Life expectancy is 2 to 5 years.
