A diagnosis of Alzheimer’s disease or dementia can be frightening both for you and your loved ones.
Suspecting you or a loved one has dementia can be extremely distressing. But the more you understand about the condition, the more you can do to improve the outcome.

What is dementia

Dementia is a degenerative cognitive disorder that manifests as a deficiency in problem solving, sustained attention, personality changes, and lapses in language and memory, often associated with the later stages of life. These changes are not part of normal aging and are severe enough to impact daily living, independence, and relationships. While Alzheimer’s disease is the most common type of dementia, there are also many other forms, including vascular and mixed dementia.

With dementia, there will likely be noticeable decline in communication, learning, remembering, and problem solving. These changes may occur quickly or very slowly over time. The progression and outcome vary, but are largely determined by the type of dementia and which area of the brain is affected.

Facing up to the possibility of dementia inevitably shifts person’s perceptions, relationships, and priorities. But experiencing symptoms doesn’t have to mean the end of your normal life. Certain types of dementia can be slowed or even reversed if caught in time. The first step is to understand what distinguishes normal memory loss from dementia symptoms, and how to identify the different types of dementia. Whatever your diagnosis, though, there can be plenty of things you can do to help slow symptoms and continue to enjoy a full and rewarding life.

Normal memory changes vs. dementia symptoms

It’s something we all have to face but the inevitable changes of aging can still be both humbling and surprising. But while experiencing wrinkling skin, fading hair color, and mild, short-term memory loss is common as we age, severe and rapid memory loss is definitely NOT a part of normal aging. In fact, many people are able to preserve their brainpower as they get older by staying mentally and physically active and making other healthy lifestyle choices.

Normal memory changes associated with aging may include

Slower thinking and problem solving – The speed of learning slows down; short-term memory takes longer to function; reaction time increases.

Decreased attention and concentration – More distractedness. All of the interruptions make learning more difficult.

Slower recall – A greater need for hints to jog the memory

Signs and symptoms of dementia

As we age, many of us experience lapses in memory. It can be worrying and confusing to realize that something you once took for granted isn’t working as well as it used to. But learning to differentiate the signs of dementia from normal aging can help to either set your mind at rest or encourage you to begin taking steps to slow or reverse the condition.

Common signs and symptoms include:

  • Memory loss
  • Impaired judgement
  • Difficulties with abstract thinking
  • Faulty reasoning
  • Inappropriate behavior
  • Loss of communication skills
  • Disorientation to time and place
  • Gait, motor, and balance problems
  • Neglect of personal care and safety
  • Hallucinations, paranoia, agitation

Someone with dementia symptoms may present as:

  • repeatedly ask the same questions
  • become lost or disoriented in familiar places
  • be unable to follow directions
  • be disoriented about the date or time of day
  • not recognize or be confused about familiar people
  • have difficulty with routine tasks such as paying the bills
  • neglect personal safety, hygiene, and nutrition

Dementia causes

In a healthy brain, mass and speed may decline in adulthood, but this miraculous organ continues to form vital connections throughout life. However, when connections are lost through inflammation, disease, or injury, neurons eventually die and dementia can develop. While the prospect of literally losing one’s self can be extremely traumatic, early intervention can dramatically alter the outcome.

In the past 20 years, scientists have greatly demystified the origins of dementia. Genetics may increase your risks, but scientists believe a combination of hereditary, environmental, and lifestyle factors are also at work.

Dementia can be caused by

Medical conditions that progressively attack brain cells and connections, most commonly seen in Alzheimer’s disease, Parkinson’s disease, or Huntington’s disease.

Medical conditions such as strokes that disrupt oxygen flow and rob the brain of vital nutrients. Additional strokes may be prevented by reducing high blood pressure, treating heart disease, and quitting smoking.

Poor nutrition, dehydration, and certain substances, including drugs and alcohol. Treating conditions such as insulin resistance, metabolic disorders, and vitamin deficiencies may reduce or eliminate symptoms of dementia.

Single trauma or repeated injuries to the brain. Depending on the location of the brain injury, cognitive skills and memory may be impaired.

Infection or illness that affects the central nervous system, including Creutzfeldt-Jakob disease and HIV. Some conditions are treatable, including liver or kidney disease, depression-induced pseudo dementia, and operable brain tumors.

Types of dementia

All dementias involve cognitive decline that can impact daily living. However, it’s important to identify the specific type of dementia in order to optimize treatment. There are several types of dementia, some of the common types are:

Alzheimer’s disease

This is the most common form of dementia, which according to the Alzheimer’s Association accounts for 60 to 80 percent of all diagnosed cases.
Alzheimer’s disease affects an estimated 1 in 10 people over age 65

Early diagnosis of Alzheimer’s can help to prolong independence and is the first step towards treatment, management, and continuing to enjoy a full life.

The following 10 warning signs may indicate that your dementia symptoms are the result of Alzheimer’s disease:

  1. Your memory loss is sufficient to disrupt your daily life. You forget things you’ve recently learned, forget important dates or events, repeatedly ask for the same information, or rely more and more on memory aides or family members.
  2. You’re having difficulties with problem-solving.You’re not able to follow plans, work with numbers, follow recipes, or keep track of bills.
  3. Having trouble completing daily tasks such as driving to a familiar place, remembering rules to a game, or completing assignments at work.
  4. Experiencing confusion over time or place.You lose track of dates, forget where you are or how you got there.
  5. Misplacing things. Putting things in strange places, being unable to retrace your steps, perhaps even accusing others of stealing.
  6. Developing problems with spoken or written words.You have difficulties following a conversation, often repeat yourself, and struggle to find the right word, or call things by the right name.
  7. Having difficulty understanding visual images.Trouble reading, judging distances, colors, or contrast, or recognizing your own reflection.
  8. Displaying poor judgement.There’s a decline in your decision making, you’re giving away large sums of money, paying less attention to personal grooming.
  9. Withdrawing from work or social activities.You have trouble remembering how to complete a work project or favorite hobby, difficulty following sports, withdraw from social events.
  10. Exhibiting changes in mood.Becoming confused, depressed, suspicious, fearful, or anxious.

Early diagnosis of Alzheimer’s can help to prolong independence and is the first step towards treatment, management, and continuing to enjoy a full life.

Vascular Dementia

This type of dementia usually follows a major stroke, or one or more silent strokes, which can happen without you realizing it. The symptoms depend on which part of the brain the stroke affected.

While Alzheimer’s usually begins with memory problems, vascular dementia more often starts with poor judgment or trouble planning, organizing, and making decisions. Other symptoms may include:

  • Memory problems that disrupt your loved one’s daily life
  • Trouble speaking or understanding speech
  • Problems recognizing sights and sounds that used to be familiar
  • Being confused or agitated
  • Changes in personality and mood
  • Problems walking and having frequent falls

Mixed dementia

This is a condition in which Alzheimer’s disease and vascular dementia occur simultaneously. The combination of the two types of dementia most commonly occurs in advanced senior years, often indicated by cardiovascular disease and dementia symptoms that get worse slowly over time.

Less common forms of dementia

Pick’s Disease affects personality, orientation and behavior. It may be more common in women and occurs at an early age.

Creutzfeldt – Jakob disease progresses rapidly along with mental deterioration and involuntary movements.

Huntington’s disease is an inherited, degenerative disease. The disease causes involuntary movement and usually begins during mid-life.

Parkinson’s disease Dementia can develop in the later stages of Parkinson’s disease, a progressive disorder of the central nervous system.

Lewy Body Dementia causes symptoms similar to Alzheimer’s disease. People with Lewy Body dementia experience hallucinations and can become fearful.

Diagnosing dementia

Obtaining an early diagnosis of dementia is critical, especially if your symptoms appear suddenly. Some medications for dementia may be more beneficial if given early in the progression of the disease. Timely intervention may also help you better control symptoms and prolong your quality of life for longer.

There is no single medical test used to diagnose dementia. To make a diagnosis, your doctor will assess your memory problems, changes in thinking, behavior, and function, and conduct medical tests to rule out other conditions and drug interactions that may be causing your symptoms.

While your doctor may be able to broadly diagnose dementia, determining the specific type can sometimes be challenging. Many symptoms overlap between different types of dementia, so you may need to consult a specialist neurologist, Geriatric psychiatrist or psychologist for a full diagnosis.

Treatment of Dementia

Obtaining an early diagnosis of dementia is critical, especially if your symptoms appear suddenly. Some medications for dementia may be more beneficial if given early in the progression of the disease. Timely intervention may also help you better control symptoms and prolong your quality of life for longer.

Coping with a diagnosis

Being diagnosed with dementia is a life-changing experience—for both you and your loved ones. It can turn your world upside down and leave you grappling with a host of conflicting emotions, from shock, anger, and grief to profound sadness and isolation. While there is currently no cure for dementia, a diagnosis doesn’t mean that your life is over. There are treatments available for the symptoms. There are also steps you can take to help slow the progression of the disease and delay the onset of more debilitating symptoms, enabling you to prolong your independence and live a rich and full life for longer.

Preventing dementia or delaying symptoms

Recent research suggests that healthy lifestyle habits and mental stimulation may help prevent dementia altogether, delay its onset, or if you’ve already been diagnosed, slow the onset of more debilitating symptoms. In fact, research published in the Journal of the American Medical Association in 2019 concluded that healthy lifestyle changes can reduce the risk of dementia even if you have a genetic predisposition. Just as physical exercise keeps you physically fit, exercising your mind and memory can help you stay mentally sharp, no matter your family history or how old you are. The following strategies can help.

  1. Regular exercise.Starting a regular exercise routine, including cardio and strength training, may significantly reduce your risk of developing dementia. Aim for 30 minutes of moderate exercise on most days of the week.
  2. Social engagement.The more socially active you are, the more you connect face-to-face with others, the stronger your memory and cognition is likely to be.
  3. Healthy diet.Brain-healthy eating habits, such as those promoted in the Mediterranean diet, can help reduce inflammation, protect neurons, and promote better communication between brain cells. Daily servings of fruit and vegetables and weekly servings of fish may help to lower your risk for dementia.
  4. Mental stimulation.By continuing to learn new things and challenge your brain, you can strengthen your cognitive skills, stay mentally sharp, and may delay or prevent dementia symptoms.
  5. Quality sleep.Getting quality sleep may help to flush out brain toxins and avoid the build-up of damaging plaques.
  6. Stress management.Unchecked stress takes a heavy toll on the brain, shrinking a key memory area, hampering nerve cell growth, and worsening dementia symptoms.
  7. Vascular health. Controlling your blood pressure, monitoring your cholesterol levels, and quitting smoking can have beneficial effects on both your heart and brain health.
