We’re all forgetful at times, regardless of our age and mental health. However, as we age, our risk of dementia increases, and by the age of 85 almost 35-percent of those in your age group with be afflicted with this degenerative disorder that causes gradually and worsening memory loss and mental skills.
If a loved shows the following 15 early warning signs of dementia, book an appointment to see a doctor immediately…
1. Memory Loss
Mild cognitive impairment (or as doctors refer to it, MCI) explains memory loss that is more pronounced than typical age-related forgetfulness. MCI will cause an inability to recall short term memory (or recent events) such as what you did yesterday or last week. However, suddenly a strong ability to remember specific from the past will occur.
A study from Rutgers University, estimates that roughly 4-percent of Americans between the ages of 65 and 74-years old have Alzheimer’s disease, with the percentage raising steady as we grow. The same research estimates that roughly 50-percent of all Americans over 85-years of age suffer with Alzheimer’s Disease and that more than half of all dementia cases are misdiagnosed and actually Alzheimer’s Disease.
2. Declining Motor Function
Difficulty with coordination and motor functions will occur as the condition progresses and can take years, but occurs when you lose the physical ability to perform routine tasks (i.e., go to the washroom, drive to your grocery store, operate the stove) and need 24-hour care for your own safety.
In a research study, published by the U.S. National Institutes of Health, researchers found that age-related cognitive and motor decline may share a common causation, meaning that the reach of Alzheimer’s disease may represent the “tip of the iceberg” of cognitive and motor dysfunction currently dubbed “normal aging” in older persons without Alzheimer’s disease and dementia.
Problems with disorientation, for example getting lost on a routine trip to the same doctor’s office you’ve been going to for years is an early sign of Alzheimer’s disease or dementia. For instance, an individual with Alzheimer’s disease suffers death of the nerve cells very gradually, over a period of years, which causes them to struggle with thinking, decision-making and memory, which makes it confusing and scary, and often causes them to withdrawal from normal day-to-day life.
For example, this may cause a sufferer to become confused or even lost when out on their own and may not be able to remember where they are, how they got there, or how and where to return home. They may gradually start to forget familiar people, places, facts, what day it is, year it is, or what time of the day it is.
4. Behavioral Changes
Personality changes that may include the opposite manners or personality traits—for example, becoming cranky when you were always easy going, becoming blissful when you were always a curmudgeon, or just being inappropriate in public can signify the onset of dementia.
Many families who have a relative with Alzheimer’s almost always admit that the behavioral and psychiatric changes are the most challenging and disturbing aspect of the disease. In the early stages, Alzheimer’s sufferers commonly become anxious, depressed, and irritable due to confusion and fear. In the later stages, Alzheimer’s sufferers can suffer with paranoia and emotional distress that shows in physical or verbal outbursts, destructive behavior, abusive behavior, delusions, and even hallucinations.
Among the behavioral and psychiatric symptoms of Alzheimer’s, paranoia is one of the most disturbing. Behavior that’s characterized as paranoid and suspicious (particularly of others in cases where the patient has the aid of a caregiver or lives in a facility) may spur from feelings that they are losing control.
Patients with Alzheimer’s can become so delusional and suspicious of those around them that they become accusatory and charge caregivers, doctors, and co-residents of theft, infidelity, and lying. As a caregiver or relative, these accusations can be extremely hurtful, which is why it’s vital to keep in mind that the disease is causing this action.
Difficulty with planning and organizing is a common early warning sign of dementia. For instance, an elderly person may suddenly have difficulty planning their grocery shopping or finding their glasses that they always put in the same location. Although the exact cause of Alzheimer’s isn’t totally clear, the disease damages and kills brain cells, leading to fewer cells and fewer healthy brain connections among surviving cells.
The deterioration of brain cells causes significant brain shrinkage in the patient that can only be determined after death, during an autopsy. However, plaque (or clumps of protein forms on the brain) causes the destruction brain cells by disrupting cell-to-cell communication, and tangles that disrupt nutrient transport to healthy brain tissues. Alzheimer’s disease is also suspected to develop due to a variety enviromental, genetic, and lifestyle factors that ultimately affect the brain.
Agitation may be triggered by a variety of things, for instance environmental factors, frustration over the inability to carry out simple tasks, the inability to communicate clearly, fatigue, or fear as “control” (i.e., driver’s license, home) is suddenly taken away. Those stricken with Alzheimer’s, are usually the first to notice that there’s an issue.
However, it will be gradual. You may first notice you have difficulty remembering dates, times, details, and thoughts. However, when you notice that these changes are also noticeable by friends, coworkers, and family members, it can lead to embarrassment, anger, and agitation, and eventually lashing out and social withdrawal.
Hallucinations or delusionary thoughts are often experienced by dementia patients, most commonly visual (seeing things that aren’t there) or auditory (hearing noises that aren’t there)—such as the belief that a caregiver is out to get them without reason. Keep in mind that those with Alzheimer’s can experience both hallucinations and delusions.
A delusion is characterized as in the believing of false things (i.e., people, memories, details, and events). However, hallucinations are different. When suffering a hallucination, an individual has a false perception. This can be a false perception of an event, objects, or person that’s sensory in nature, meaning patients with Alzheimer’s can actually feel, hear, see, taste, and smell things that don’t really exist.
9. Sexual Actions
It’s common for dementia patients to suddenly become sexual without awareness that their actions are inappropriate—for instance, removing clothing, exposing oneself in public, or touching and saying tasteless things to strangers and caregivers. This inappropriate sexual behavior can be embarrassing and even frightening for loved ones and caregivers.
These inappropriate and often aggressive sexual behaviors are part of the disease. For instance, a patient may become sexually disinhibited (or bold) as damage becomes more severe in the brain’s frontal and temporal lobes, which is the area that manages control response.
10. Cognitive Decline
This could be as simple as an inability to reason or a more drastic decline in cognitive functions—such as thinking, learning, reading and retaining information, problem solving, language and speech. Clinical researchers at the New York University School of Medicine’s Silberstein Aging and Dementia Research Center, point out that not all individuals experience the same rate of cognitive decline. For instance, many in the early stages of dementia show no memory loss or decrease in decision making abilities.
However, cognitive decline can enter in the mid- and later stages of the disease, resulting in trouble with memory, performance of mundane daily tasks, losing objects, the inability to use the right word, forgetting names or people, and trouble with planning, remember dates, and organizational skills.
11. Apathy and Withdrawal
Apathy is another common warning sign of dementia, as it tends to occur early on. When a person experiences this symptom they may lose interest in things they previously enjoyed, like hobbies or favorite activities.
Those who are close to them, like friends and family, may also notice that they become withdrawn. This is also due to apathy, and a loss of interest in being social. They can become largely uncommunicative, and when they do engage with others, they can come across as emotionally flat.
12. Reduced Concentration
As dementia progresses, those affected tend to be easily distracted and have trouble focusing, which makes it increasingly harder for them to concentrate for any length of time.
This not only affects their ability to learn and memorize new information, but can make also it difficult for them to follow along with storylines on television shows, movies, or those being told to them by another person. Healthline.com adds that they may also “forget the meanings of words they hear or struggle to follow along with conversations,” whether on TV or in real life.
13. Difficulty with Complex Tasks and Abstract Thinking
Dementia can make doing complex tasks far more difficult than they previously would have been. And multitasking may be even more challenging, as cognitive decline requires that the brain focus on one thing at a time.
Abstract thinking is also problematic for people with dementia. For instance, they may have trouble understanding the numbers on a calculator or, when balancing a checkbook, Dementia Australia says they “could forget completely what the numbers are and what needs to be done with them.”
14. Impaired Judgment
Because a person’s memory and concentration are both affected by dementia, so too is their judgment. One way that this may be noticeable is in their choice of clothing with respect to the weather, like “wearing light clothing on a cold day,” says the Alzheimer Society of Canada.
The source adds that “not recognizing a medical problem that needs attention” is another indication of impaired judgment. As is making poor decisions when driving; decisions that not only endanger themselves, but other drivers and pedestrians as well.
15. Disrupted Sleep
Those with dementia, especially Alzheimer’s disease, may find that they develop problems sleeping. Although the Alzheimer’s Association says it’s not entirely clear why these problems occur, it’s believed that “sleep changes somehow result from the impact of Alzheimer’s on the brain.”
Common sleep changes or disturbances that occur with Alzheimer’s disease include difficulty sleeping, where they “wake up more often and stay awake longer during the night,” as well as shifts in the sleep cycle. For instance, they may feel very tired during the day, which they remedy by napping, but then when it’s time for bed at night they aren’t tired and just lay there wide awake, thus perpetuating the cycle.
