What are Common Symptoms and Types of Dementia

It is human nature that we try to do everything possible to slow the aging process. We take vitamins and supplements, get plastic surgery, slather our bodies in lotions and potions, all so that we don’t appear the age we are. In addition, we change our diets and work out, doing almost anything to defy nature. And while we may look great on the outside, there are some things that we cannot control that may be happening on the inside. Continue reading to discover more about dementia and some of the common symptoms, and different descriptions and names of dementia based on symptoms.

What is Dementia?

Dementia is an umbrella of illnesses and symptoms with a lot of medical conditions under it that affect older adults. A wide range of medical conditions cause symptoms such as memory loss, problem-solving, cognitive abilities, and other issues that drive the quality of life to deteriorate. A lot of times, before a diagnosis of dementia, older adults are thought of as senile.

The cause of dementia is damaged brain cells that mess with the brain cells’ ability to communicate. The lack of communication causes those affected to act differently than usual.

Dementia is a progressive illness which means that the symptoms start slowly and gradually get worse. Dementia also involves several diseases that are diagnosed based on what part of the brain cells are damaged. Some of those symptoms include:

  • Short term memory loss
  • Confusion
  • Trouble communicating
  • Inability to understand certain communications
  • Unable to perform certain tasks
  • Repetition
  • Loss of interest

Alzheimer’s Disease

Alzheimer’s Disease is the most common type of dementia, representing 60-80% of all dementia cases. The average age for patients with Alzheimer’s is 65 years old. Diagnosis before this age is considered early onset. It usually starts with memory loss and progresses into more confusion and failure to thrive as a progressive disease. Patients typically live with Alzheimer’s Disease for 4-8 years after diagnosis but can also live up to 20 years.

There are no cures for Alzheimer’s Disease, but medication and surgery can slow the progression.

The part of the brain affected by Alzheimer’s Disease is the learning part. Patients may suffer from disorientation, mood and behavior changes, confusion about dates and times. They may also become distrustful of family members.

Vascular Dementia

Vascular dementia happens due to reduced blood flow to the brain, especially from a stroke or heart attack. It can be sudden or gradual. Vascular dementia affects memory, thinking, and reasoning. Some of the early symptoms of vascular dementia are slow thought, judgment, depression, and having trouble understanding information. Some signs may go unnoticed, but high blood pressure, diabetes, high cholesterol, and smoking raise an aging individual’s risk of dementia.

  • In addition to the above, some other symptoms of vascular dementia are:
  • Difficulty deciding what to do next
  • Restlessness and agitation
  • Unsteady gait
  • Sudden or frequent urge to urinate
  • Reduced ability to organize thoughts or actions

Lewy Bodies

Lewy Bodies Dementia (LBD) is very similar to Alzheimer’s Disease. However, it progresses more quickly than other types of dementia. Although there are no cures for LBD, there is medication to help with symptoms. The overlap in symptoms between LBD and Parkinson’s makes them hard to diagnose and distinguish. A symptom not common in the other types of dementia are:

  • Sleep disturbances
  • Visual hallucinations
  • Delusions
  • Problems with interpreting visual information

Another difference seen more common in LBD is a disruption of the autonomic nervous system. This disruption causes the patient’s blood pressure to drop, making them dizzy, fall more frequently, and suffer urinary incontinence.

Parkinson’s Disease

Tremors, muscular rigidity mark Parkinson’s Disease, and slow movements, and reduced facial expressions. It is a progressive disease of the nervous system associated with the degeneration of the neurotransmitter dopamine in the brain. Genes and environmental factors may play a role in the development of Parkinson’s Disease. Some of the signs of Parkinson’s Disease are:

Shaking limbs – usually hands or fingers

  • Speech changes
  • Writing changes
  • Impaired posture and balance
  • Rigid muscles

As you have read, regardless of how well we take care of ourselves, there are some things that happen in life that cannot be controlled. Dementia is an umbrella of illnesses with symptoms that are similar but have different effects. Four types of dementia and their symptoms are above.

Alzheimer’s: Signs & Symptoms

 

Alzheimer’s disease (AD) is the most common type of dementia seen in older adults. An estimated 5.4 million Americans of all ages had Alzheimer’s disease in 2012. Nearly half (45%) of people over the age of 85 have AD. By 2050, the number of individuals age 65 and over with Alzheimer’s could range from 11 million to 16 million unless science finds a way to prevent or effectively treat the disease. One in eight older adults has AD, and it is the sixth leading cause of death in the United States (Alzheimer’s Association, 2012). Those affected with AD may live from 3–20 years or more after diagnosis, making the life span with this disease highly variable.

Risk factors

Advanced age is the single most significant risk factor for AD (Alzheimer’s Association, 2012). More women than men have AD, but this is because women live longer than men, not because gender is a risk factor. Family history and heredity are also identified risk factors for AD, as are head trauma and poor cardiac health.

Warning Signs

Alzheimer’s disease is characterized by progressive memory loss. The person affected by AD is gradually less able to remember new information and memory lapses begin to affect daily function. It is a terminal disease that over its course will eventually leave a person completely dependent upon others for care.

Diagnosis

Initially, the clinical progression of the disease is slow with mild decline; however, deterioration increases the longer the person lives, with an average life span of 8 years after diagnosis (Cotter, 2002; Fletcher, Rapp, & Reichman, 2007). The underlying pathology is not clear, but a growth of plaques and fibrillary tangles, loss of synapses, and neuronal cell loss are key hallmarks of AD that interfere with normal cell growth and the ability of the brain to function. Absolutely definitive diagnosis is still through autopsy, although clinical guidelines make diagnosis easier than decades ago when less was known about the disease. Primary care physicians generally make the diagnosis through a thorough history, physical exam, cognitive testing, and labs. New criteria for diagnosis include staging the disorder and biomarkers (beta amyloid and tau in the cerebrospinal fluid and blood) (Alzheimer’s Association, 2012b). An MRI of the brain may be ordered to rule out other causes of symptoms.

The clinical course of AD is divided into several stages, depending on the source consulted. In the early course of AD, the person may demonstrate a loss of short-term memory. This involves more than common memory loss, such as where the keys were put, and may involve safety concerns such as forgetting where one is going while driving. The inability to perform math calculations and to think abstractly may also be evident. In the middle or moderate phase, many bodily systems begin to decline. The person may become confused as to date, time, and place. Communication skills become impaired and personality changes may occur. As cognitive decline worsens, the person may forget the names of loved ones, even their spouse. Wandering behavior as well as emotional changes, screaming, delusions, hallucinations, suspiciousness, and depression are common. The person with AD is less able to care for her- or himself and personal hygiene suffers. In the most severe and final phase, the person becomes completely dependent upon others, experiences a severe decline in physical and functional health, loses communication skills, and is unable to control voluntary functions. Death eventually results from body systems shutting down and may be accompanied by an infectious process. Although there is no single test, and the diagnosis may be one of exclusion, early diagnosis is important to maximize function and quality of life for as long as possible. Persons experiencing recurring and progressing memory problems or difficulties with daily activities should seek professional assistance from their physician.

Treatment

Treatment for AD is difficult. There are several medications (such as Aricept, Namenda, Razadyne, and Exelon) that may help symptoms (such as memory), but they do not slow the course of the disease. There is currently no cure; however, research continues to occur in pharmacology, nonpharmacology, and the use of stem cells to manage symptoms and perhaps one day eradicate the disease.

Treatment will focus on symptom management, particularly in the areas of behavior, safety, nutrition, and hygiene. Behavioral issues such as wandering and outbursts pose a constant challenge. Many long-term care facilities have special “memory care” units to care for Alzheimer’s patients from the early to late stages of the disease. These units provide great benefits such as consistent and educated caregivers with whom the patient or resident will be familiar, a safe and controlled environment, modified surroundings to accommodate wandering behaviors, and nursing care 24 hours a day. Additionally, nurses are present to manage medications and document outcomes of therapies. However, many family members wish to care for their loved ones at home for as long as possible.

Thus, another important aspect of care in AD is care for the caregivers. Howcroft (2004) suggested that “support from carers is a key factor in the community care of people with dementia, but the role of the caregiver can be detrimental to the physical, mental, and financial health of a carer” (p. 31). She goes on to say that the caregivers of persons with AD would benefit from training in how to cope with behaviors that arise in these patients and how to cope with practical and legal issues that may occur.

Research has shown that ongoing skills are needed by family caregivers to deal with the progressive decline caused by AD. In fact, “a 63% greater risk of mortality was found among unpaid caregivers who characterized themselves as being emotionally or mentally strained by their role versus noncaregivers” (National Conference of Gerontological Nursing Practitioners & National Gerontological Nursing Association, 2008b, p. 4). Adapting to stress, working on time management, maximizing resources, and managing changing behavior were all skills caregivers needed to develop in order to successfully manage home care of their loved ones. When interventions and resources were not used by caregivers in the early stages of the care recipient’s AD, the risk of a healthy patient being institutionalized due to caregiver burden was higher (Miller, Rosenheck & Schneider, 2012). Caregivers needed not only to acquire knowledge and skills, but also to make emotional adjustments themselves to the ever-changing situation.

Such findings suggest that nurses should focus a good deal of time on educating caregivers of persons with AD to cope with, as Nancy Reagan put it, “the long good-bye.” Scientists continue to explore the causes of AD and hope in the near future to be able to isolate the gene that causes it. In the meantime, results from a fascinating longitudinal study (called the Nun study) on aging and AD, which used a group of nuns who donated their brains to be examined and autopsied after death, has suggested that there is a connection between early “idea density” and the emergence of AD in later life. That is, essays the nuns wrote upon entry to the convent were analyzed and correlated with those who developed AD. It was found that those with lower idea density (verbal and linguistic skills) in early life had a significantly greater chance of developing AD (Grossi, Buscema, Snowdon, & Antuono, 2007; Snowdon, 2004). The nun study has allowed researchers to examine hundreds of brains so far in nuns who died between 75 and 107 years of age and discover other important facts such as a relationship between stroke and the development of AD in certain individuals, and the role of folic acid in protecting against development of AD (Snowdon, 2004). Scientists from a number of fields continue to research the causes and possible treatments for AD and the Nun study project is continuing at the University of Minnesota. Snowdon’s research suggests that early education, particularly in verbal and cognitive skills, may protect persons from AD in later life.

Guest Blog: Tips on Caring for Loved Ones with Dementia

Dementia is a chronic or progressive syndrome that affects a person’s thinking, memory, comprehension, orientation, language, learning capacity, judgment, and calculation. People with dementia slowly lose their cognitive abilities, which leads to a decline in their social behavior and emotional control. Dementia develops when the brain is injured or damaged, such as what happens to individuals with Alzheimer’s disease.

According to the Alzheimer’s Association, over five million Americans are currently dealing with Alzheimer’s dementia. An estimated 80% are seniors aged 75 and up. If proper care, attention, and medication are not prioritized, the total can balloon to 13 million by 2050. Medical and health facilities are doing every means possible to address the situation.

If your senior family member has dementia and living at home or is under assisted living care, your best contribution is to care for your loved one properly. Here are tips to help you out.

 Ask simple questions.

Someone with dementia will find open-ended questions confusing and intimidating. Instead of asking “what” questions, try to rephrase them to “yes-no” questions. For example, instead of asking, “What time would you like to take a bath today?” try asking, “Would you like to take a bath at 4 pm?”

Keep your words simple and clear.

 Allow your loved one to help with daily tasks.

When dementia progresses, your loved one may find it difficult to remember and focus on tasks. You can help him or her maintain daily activities and skills and stay active. Allow him or her to assist you with simple activities such as setting the table, making the bed, and gardening. Help your loved one remember tasks and things by placing memory aids, such as signs and labels, all over the house.

 Take your loved one to lunch.

Keeping senior loved ones with dementia socially active is essential. Have lunch together at his or her favorite restaurant. Go to a place where he or she used to frequent when communication wasn’t yet a problem. Make your loved one feel special and important.

 Hold and touch your loved one.

Your touch is very powerful and reassuring. Hold your loved one’s hand or stroke his or her face now and then. Let him or her feel your love and support.

Most important of all, ask for help. Talk to a caregiver or get in touch with an assisted living care facility.
