The Silent Transformation: Understanding Dementia
A comprehensive look at the challenges of Alzheimer's disease, from effective prevention strategies and early diagnosis to the significant benefits of home-based medical care for maintaining patient dignity
Dementia is not a singular diagnosis, but rather an umbrella term for a group of diseases that impair the brain's ability to function. Among these, Alzheimer's disease is the most common challenge facing aging families today.
The hallmark of Alzheimer's is its gradual onset, typically beginning with memory lapses before expanding to affect every area of daily life. However, Dr. Inbal Mayan, a geriatric specialist sub-specializing in dementia and cognitive disorders and the medical director of Sabar Health – Hospital at Home, emphasizes that we must distinguish between normal aging and the disease.
"It is very important to calm people down — not every forgetful moment is Alzheimer's," Dr. Mayan explains. "If I don't remember where I put my keys, that isn't Alzheimer's. It becomes a concern when it's a lack of orientation — not understanding where you are or failing to recognize someone you know".
Interestingly, the patient is often the last to know. Usually, it is the family members who first notice a persistent change in behavior over time. The diagnostic journey often starts with a family doctor who conducts blood tests and imaging. Crucially, these initial tests are not to "find" Alzheimer's, but to rule out other dangerous or treatable conditions. Once those are cleared, the patient is referred to a memory clinic for a formal diagnosis by a specialist.
Prevention is Possible
"While approximately 60% of cases occur across all populations regardless of ethnicity or religion, the remaining 40% of Alzheimer's cases are considered preventable", says Dr. Mayan. She highlights that brain health is inextricably linked to heart health. The recipe for prevention includes physical activity, nutrition, cognitive engagement: Using the brain through reading, crossword puzzles, and Sudoku, social stimulation: Regularly meeting people and staying socially active, sensory care: Treating hearing and vision loss is vital.
"A person with untreated hearing loss has a higher chance of developing Alzheimer's," Dr. Mayan warns. This is because hearing loss often leads to social withdrawal and reduced mental stimulation, which accelerates decline. She notes that this prevention should ideally start early in life by managing blood pressure and sugar levels, as chronic hypertension over many years significantly impacts cognitive health.
Maximizing quality of life
While there is currently no cure for Alzheimer's, the focus of modern geriatric medicine is on maximizing quality of life. One of the most significant insights Dr. Mayan shares involves the environment in which we treat the elderly.
For a person with dementia, a standard hospital can be a detrimental environment. The unfamiliar surroundings, the constant hum of fluorescent lights that blur the line between day and night, and prolonged bed rest can lead to a severe functional decline from which many patients never recover.
"These patients often deteriorate after hospitalization and do not return to their previous functional state," says Dr. Mayan.
One of the most common alternatives is home-based hospitalization. Dr. Mayan says that research showed that medical outcomes at home are equal to, or even better than, those in a hospital. In the comfort of their own home, patients have access to familiar food, their own clothes, and a safe environment. This also eases the burden on family members, who no longer need to commute to a facility.
Essential Tips for Families
Navigating an approximately 10-year journey (from diagnosis to death) with Alzheimer's is an emotional and logistical marathon. Dr. Mayan offers three key pillars of advice for families:
1. Early Planning: While the patient is still able to understand, establish medical and financial powers of attorney. This prevents family conflict later and ensures the medical team knows exactly how to proceed.
2. Seek Diagnosis for Rights: A formal diagnosis is not just about a label; it unlocks rights and benefits from national insurance and health funds.
3. Support for the Caregiver: Watching a strong parent figure transform into someone who requires constant care is a profound hardship. "Caregivers need support themselves within this process", Dr. Mayan insists.
