Dementia is a cluster of chronic, progressive diseases that damage the brain, so a Dementia diagnosis can eventually come with sweeping changes to a person’s cognitive abilities.

This damage is responsible for all the hallmark symptoms of the disease that lead many people to require home care assistance: staggering memory loss, mobility impairments, and communication issues.

But Dementia can also produce significant changes in a person’s personality and behaviour. You might notice your loved ones not acting like themselves as the disease progresses. They might do or say things they would have never done before living with Dementia.

While it can be extremely upsetting to see a parent or partner behaving out of character, it’s a normal and an expected speedbump. Understanding how and why Dementia affects a person’s personality and behaviour may help you cope with these changes.

Changes in the Brain: Why Dementia Alters Personality and Behaviour

While there are many kinds of Dementia, these diseases affect the brain by damaging neurons and their connections. In other words, brain cells die off, and they don’t grow back.

When it comes to a person’s temperament, neuron damage to the frontal, temporal, and parietal lobes is often responsible for the biggest changes in your loved one’s personality and behaviour. Together, these three lobes are responsible for many cognitive functions, including decision-making, emotional responses, executive functions, language processing, and memory encoding.

Dying and dead brain cells can affect people differently depending on the area of the brain that’s damaged. The location of this damage can even cause different symptoms. It may cause difficulty understanding conversations and social queues, leading someone to withdraw or express anger when they’re confused. It can also lead to impulsive behaviour, causing someone to undress in a public space or speak unkindly to a loved one.

Other Reasons Why Dementia Changes Personality and Behaviour

You can’t blame every personality and behavioural change on a person’s declining cognitive abilities, especially in the early stage of the disease.

It’s important to remember that a Dementia diagnosis can be frustrating and scary. You or your loved one might be dealing with feelings of anger, anxiety, and anticipatory grief about the future, all of which can affect moods and habits.

As the disease progresses and treatments change, other factors may impact a person’s temperament.

  • They may feel frustrated and depressed when they can no longer pursue hobbies that they enjoy.
  • Some people living with Dementia may struggle to sleep well, and chronic sleep issues can lead to anxiety, poor concentration, and irritability.
  • New medication can negatively impact their mood or come with other side effects.
  • As their ability to communicate deteriorates, they may act out when they feel pain or need help with Activities of Daily Life (ADLs).

If a Senior struggles to communicate their needs or requires assistance with ADLs, they likely require round-the-clock care. While some families think a nursing facility may be the only solution, Integracare is an option for those who want to manage their Dementia in the comfort of their own home.
