Is it Dementia or Are You Forgetful?

Memory loss can be a normal part of aging, but dementia is not. While occasional forgetfulness is common, dementia involves a significant decline in cognitive functioning that interferes with daily life, as explained by the National Institute on Aging. As a physician I have taken care of patients in the outpatient setting, inpatient setting and even in the long term care setting and I have seen patients with dementia come in many sizes. Quite often I am asked by the families just how can they tell whether their loved one is just dealing with old age and forgetfulness or is this the start of dementia.

What is Alzheimer's Dementia

Alzheimer's dementia is the most common form of dementia, accounting for 60-80% of all dementia cases. It is a progressive brain disorder that slowly destroys memory, thinking skills, and eventually the ability to carry out simple tasks. Alzheimer's disease is characterized by the abnormal buildup of proteins in the brain, specifically amyloid plaques and tau tangles, which lead to the death of brain cells. Symptoms typically begin with mild memory loss and gradually worsen over time, affecting cognitive functions such as language, problem-solving, and reasoning. While the exact cause is not fully understood, factors such as age, genetics, and lifestyle may contribute to its development. Alzheimer's disease primarily affects individuals over 65, though early-onset cases can occur in people in their 30s to mid-60s.

Early Warning Signs of Dementia

Early warning signs of dementia include memory loss that disrupts daily life, difficulty completing familiar tasks, confusion about time or place, problems with language, and changes in mood or personality. Other indicators are trouble with planning or problem-solving, misplacing items and inability to retrace steps, poor judgment, withdrawal from work or social activities, and challenges with visual perception. These signs often develop gradually and may vary between individuals. While occasional forgetfulness is normal with aging, persistent cognitive changes that interfere with daily functioning warrant medical evaluation to determine the underlying cause and explore potential treatment options.

Impact of Dementia on Daily Life

This is probably one of the biggest factors associated with dementia, the impact that it has on one's daily activities of life. When we talked with Niesia Garza, LCSW she discussed the impact it had on families.

Dementia significantly affects a person's ability to perform everyday activities, impacting various aspects of daily life. As the disease progresses, individuals may struggle with executive functioning, making it challenging to complete simple tasks like showering or getting dressed. Memory loss, both short-term and long-term, can interfere with routine activities such as making a cup of tea or putting on clothes. Judgment and decision-making abilities are also affected, potentially leading to unsafe situations like leaving the oven on.

People with dementia often require assistance with complex tasks such as managing finances and maintaining a household. Additionally, dementia can cause changes in behavior and mood, affecting social interactions and relationships. As the condition advances, individuals may need increasing support for basic activities of daily living, including eating, dressing, and personal hygiene.

Becoming forgetful is apart of the process of getting older but quite often I have patients and their family members who are afraid that the symptoms they are experiencing maybe early signs of dementia so I have to talk them away from the ledge. Unlike dementia, normal age-related forgetfulness does not significantly disrupt daily life or independence. Common examples include occasionally forgetting names, misplacing items, or taking longer to recall information. These memory lapses are generally manageable and do not impair one's ability to function independently, work, or maintain social relationships.

It's important to remember that while some degree of memory decline is normal with age, major cognitive abilities often remain largely unaffected. Factors such as stress, lack of sleep, certain medications, and nutritional deficiencies can also contribute to memory issues in older adults. To maintain cognitive health, experts recommend staying mentally active, exercising regularly, maintaining a healthy diet, and addressing underlying health conditions that may affect memory.

Causes of Memory Loss That Are Reversible

Several medical conditions can cause dementia-like symptoms that may be reversible with proper treatment. Common reversible causes include vitamin B12 deficiency, thyroid disorders, depression, medication side effects, and infections like urinary tract infections. Normal pressure hydrocephalus, a buildup of cerebrospinal fluid in the brain, can also mimic dementia symptoms but may be treatable with surgery. Dehydration, sleep apnea, and certain nutritional deficiencies can lead to cognitive impairment that resolves with appropriate interventions. Additionally, some metabolic and endocrine conditions like hypothyroidism may cause reversible cognitive decline. Early identification and treatment of these underlying causes is crucial, as addressing them promptly can potentially reverse the dementia-like symptoms and improve cognitive function.

Diagnostic Testing Available For Dementia

There is a comprehensive approach to test for dementia, I often tell patient's families that dementia is something that we have to rule in after ruling after possible thing that could be causing the behavior and memory changes out. The process typically begins with a thorough medical history review and physical examination. Cognitive assessments, such as the General Practitioner Assessment of Cognition (GPCOG), are used to evaluate memory, thinking skills, and problem-solving abilities. Blood tests are conducted to rule out other conditions that may cause dementia-like symptoms, checking liver, kidney, and thyroid function, as well as vitamin B12 levels and diabetes markers. Brain imaging, including MRI or CT scans, may be used to detect structural changes or damage. In some cases, more specialized tests like PET scans, genetic testing, or cerebrospinal fluid analysis may be recommended. The diagnosis is based on a combination of these assessments, as there is no single definitive test for dementia.

Treatment Options For Dementia

Treatment options for dementia primarily focus on managing symptoms and improving quality of life, as there is currently no cure. For Alzheimer's disease and some other forms of dementia, medications called cholinesterase inhibitors (donepezil, rivastigmine, and galantamine) may temporarily improve memory and cognitive function. Memantine is another medication used for moderate to severe Alzheimer's disease. Non-pharmacological approaches include cognitive stimulation therapy, reminiscence work, and cognitive rehabilitation, which can help maintain cognitive function and improve well-being. Lifestyle modifications such as regular exercise, a healthy diet, and staying socially active are also recommended. For potentially reversible causes of memory loss, treating the underlying condition (e.g., vitamin B12 deficiency, thyroid disorders) may resolve symptoms. It's important to note that treatment plans should be tailored to individual needs and may involve a combination of approaches under medical supervision.
