Early indicators of dementia: 5 behaviour changes to look for after age 50
Calgary (Canada) (The Conversation): Dementia is often thought of as a memory problem, like when an elderly person asks the same questions or misplaces things. In reality, individuals with dementia will not only experience issues in other areas of cognition like learning, thinking, comprehension and judgement, but they may also experience changes in behaviour.
It's important to understand what dementia is and how it manifests. I didn't imagine my grandmother's strange behaviours were an early warning sign of a far more serious condition.
She would become easily agitated if she wasn't successful at completing tasks such as cooking or baking. She would claim to see a woman around the house even though no woman was really there. She also became distrustful of others and hid things in odd places.
These behaviours persisted for some time before she eventually received a dementia diagnosis.
Cognitive and behavioural impairment
When cognitive and behavioural changes interfere with an individual's functional independence, that person is considered to have dementia. However, when cognitive and behavioural changes don't interfere with an individual's independence, yet still negatively affect relationships and workplace performance, they are referred to as mild cognitive impairment (MCI) and mild behavioural impairment (MBI), respectively.
MCI and MBI can occur together, but in one-third of people who develop Alzheimer's dementia, the behavioural symptoms come before cognitive decline.
Spotting these behavioural changes, which emerge in later life (ages 50 and over) and represent a persistent change from longstanding patterns, can be helpful for implementing preventive treatments before more severe symptoms arise. As a medical science PhD candidate, my research focuses on problem behaviours that arise later in life and indicate increased risk for dementia.
Five behavioural signs to look for
There are five primary behaviours we can look for in friends and family who are over the age of 50 that might warrant further attention.
1. Apathy
Apathy is a decline in interest, motivation and drive.
An apathetic person might lose interest in friends, family or activities. They may lack curiosity in topics that normally would have interested them, lose the motivation to act on their obligations or become less spontaneous and active. They may also appear to lack emotions compared to their usual selves and seem like they no longer care about anything.
2. Affective dysregulation
Affective dysregulation includes mood or anxiety symptoms. Someone who shows affective dysregulation may develop sadness or mood instability or become more anxious or worried about routine things such as events or visits.
3. Lack of impulse control
Impulse dyscontrol is the inability to delay gratification and control behaviour or impulses.
Someone who has impulse dyscontrol may become agitated, aggressive, irritable, temperamental, argumentative or easily frustrated. They may become more stubborn or rigid such that they are unwilling to see other views and are insistent on having their way. Sometimes they may develop sexually disinhibited or intrusive behaviours, exhibit repetitive behaviours or compulsions, start gambling or shoplifting, or experience difficulties regulating their consumption of substances like tobacco or alcohol.
4. Social inappropriateness
Social inappropriateness includes difficulties adhering to societal norms in interactions with others.
Someone who is socially inappropriate may lose the social judgement they previously had about what to say or how to behave. They may become less concerned about how their words or actions affect others, discuss private matters openly, talk to strangers as if familiar, say rude things or lack empathy in interactions with others.
5. Abnormal perceptions or thoughts
Abnormal perception or thought content refers to strongly held beliefs and sensory experiences.
Someone with abnormal perceptions or thoughts may become suspicious of other people's intentions or think that others are planning to harm them or steal their belongings. They may also describe hearing voices or talk to imaginary people and/or act like they are seeing things that aren't there.
Before considering any of these behaviours as a sign of a more serious problem, it's important to rule out other potential causes of behavioural change such as drugs or medications, other medical conditions or infections, interpersonal conflict or stress, or a recurrence of psychiatric symptoms associated with a previous psychiatric diagnosis. If in doubt, it may be time for a doctor's visit.
The impact of dementia
Many of us know someone who has either experienced dementia or cared for someone with dementia. This isn't surprising, given that dementia is predicted to affect one million Canadians by 2030.
While people between the ages of 20 and 40 may think that they have decades before dementia affects them, it's important to realize that dementia isn't an individual journey. In 2020, care partners including family members, friends or neighbours spent 26 hours per week assisting older Canadians living with dementia. This is equivalent to 235,000 full-time jobs or
7.3 billion annually.
These numbers are expected to triple by 2050, so it's important to look for ways to offset these predicted trajectories by preventing or delaying the progression of dementia.
Identifying those at risk
While there is currently no cure for dementia, there has been progress towards developing effective treatments, which may work better earlier in the disease course.
More research is needed to understand dementia symptoms over time; for example, the online CAN-PROTECT study assesses many contributors to brain aging.
Identifying those at risk for dementia by recognising later-life changes in cognition, function as well as behaviour is a step towards not only preventing consequences of those changes, but also potentially preventing the disease or its progression. (The Conversation)

Trouble ‘Miyas’ everywhere only then they will leave Assam: Himanta Biswa Sarma
Says “Himanta Biswa Sarma, BJP are openly against them, we are saying it openly
New Delhi: Assam Chief Minister Himanta Biswa Sarma on Tuesday said that four to five lakh “Miya voters” would be removed from the electoral rolls in the state once the Special Intensive Revision (SIR) of voter lists is carried out. He also made a series of controversial remarks openly targeting the Miya community, a term commonly used in Assam in a derogatory sense to refer to Bengali-speaking Muslims.
Speaking to reporters on the sidelines of an official programme in Digboi in Tinsukia district, Sarma said it was his responsibility to create difficulties for the Miya community and claimed that both he and the BJP were “directly against Miyas”.
“Four to five lakh Miya votes will have to be deleted in Assam when the SIR happens,” Sarma said, adding that such voters “should ideally not be allowed to vote in Assam, but in Bangladesh”. He asserted that the government was ensuring that they would not be able to vote in the state.
The chief minister was responding to questions about notices issued to thousands of Bengali-speaking Muslims during the claims and objections phase of the ongoing Special Revision (SR) of electoral rolls in Assam. While the Election Commission is conducting SIR exercises in 12 states and Union Territories, Assam is currently undergoing an SR, which is usually meant for routine updates.
Calling the current SR “preliminary”, Sarma said that a full-fledged SIR in Assam would lead to large-scale deletion of Miya voters. He said he was unconcerned about criticism from opposition parties over the issue.
“Let the Congress abuse me as much as they want. My job is to make the Miya people suffer,” Sarma said. He claimed that complaints filed against members of the community were done on his instructions and that he had encouraged BJP workers to keep filing complaints.
“I have told people wherever possible they should fill Form 7 so that they have to run around a little and are troubled,” he said, adding that such actions were meant to send a message that “the Assamese people are still living”.
In remarks that drew further outrage, Sarma urged people to trouble members of the Miya community in everyday life, claiming that “only if they face troubles will they leave Assam”. He also accused the media of sympathising with the community and warned journalists against such coverage.
“So you all should also trouble, and you should not do news that sympathise with them. There will be love jihad in your own house.” He said.
The comments triggered reactions from opposition leaders. Raijor Dal president and MLA Akhil Gogoi said the people of Assam had not elected Sarma to keep one community under constant pressure. Congress leader Aman Wadud accused the chief minister of rendering the Constitution meaningless in the state, saying his remarks showed a complete disregard for constitutional values.
According to the draft electoral rolls published on December 27, Assam currently has 2.51 crore voters. Election officials said 4.78 lakh names were marked as deceased, 5.23 lakh as having shifted, and 53,619 duplicate entries were removed during the revision process. Authorities also claimed that verification had been completed for over 61 lakh households.
On January 25, six opposition parties the Congress, Raijor Dal, Assam Jatiya Parishad, CPI, CPI(M) and CPI(M-L) submitted a memorandum to the state’s chief electoral officer. They alleged widespread legal violations, political interference and selective targeting of genuine voters during the SR exercise, describing it as arbitrary, unlawful and unconstitutional.
