Can Mom’s Dementia Be Fixed?

You likely know someone living with dementia — but what if a loved one’s symptoms aren’t what they seem? Could that dementia be reversible? According to the 2025 Alzheimer’s Disease Facts and Figures report from the Alzheimer’s Association, the number of Americans age 65 and older living with Alzheimer’s dementia has climbed to approximately 7.2 million—up from an estimated 6.9 million in 2024. 

This means about 11% of older adults now live with the disease, or about one in nine people over age 65. These figures focus on clinical dementia due to Alzheimer’s, referring to individuals experiencing cognitive decline severe enough to interfere with daily life. They do not include those in earlier stages — such as mild cognitive impairment due to Alzheimer’s — or individuals who have Alzheimer’s biomarkers but no noticeable symptoms.

When these earlier stages are included, the Alzheimer's Association estimates that 10 million to 12 million older Americans across all stages of memory impairment may be affected.

In addition, roughly 200,000 Americans under 65 are living with early-onset Alzheimer’s, where symptoms begin before age 65. These individuals often face more aggressive disease patterns and unique challenges with employment, insurance and family responsibilities. While this group is relatively small compared with the total number affected, the impact on families and communities is profound.

• 7.2 million Americans aged 65+ with clinical Alzheimer’s dementia
• ≈11% prevalence among older adults
• 200,000 Americans under 65 with early-onset Alzheimer’s (estimate unchanged)
• 10–12 million older adults across all clinical stages, including MCI

These updated figures highlight a continuing upward trend in Alzheimer’s prevalence in 2025—a result of both longevity in the aging population and enhanced diagnostic practices. And while Alzheimer’s is the most common form, there are many other types of dementia — all of which take an emotional and financial toll on families. 

But here’s the part many people don’t realize: several reversible or treatable conditions can look like dementia, and getting a correct diagnosis could restore your loved one’s memory, clarity, and quality of life. So could mom's dementia be reversed? Perhaps. 

Conditions That Can Mimic Dementia 

Experts emphasize the importance of having family members evaluated by a physician familiar with cognitive health. Several conditions can cause dementia-like symptoms that may be treatable or reversible:

• Hearing or vision loss: These sensory deficits can lead to confusion and social withdrawal.

• Oxygen deprivation: Heart or lung problems that restrict oxygen to the brain can result in temporary cognitive decline.

• Infections and delirium: Urinary tract infections or hospital-induced delirium, especially in older adults, can cause sudden, severe confusion that typically resolves with treatment.

• Dehydration: This is a common but overlooked cause of cognitive changes in seniors.

• Vitamin B12 deficiency: This condition can mimic dementia but is often reversible with supplements.

• Medications: Side effects, drug interactions, or overmedication can cause memory loss and disorientation.

• Brain tumors: These or other underlying illnesses may first present as cognitive symptoms.

• Post-surgical issues: Cognitive decline following major procedures, such as open-heart surgery, can affect memory either temporarily or permanently.

"Cognitive decline doesn’t always mean dementia," said Dr. Elise Caccappolo, associate professor of neuropsychology at Columbia University Medical Center. "Simple health issues can sometimes masquerade as Alzheimer’s, and a careful medical evaluation is key."

Don’t Overlook Hormonal or Mental Health Factors

Even younger adults can experience temporary cognitive symptoms. For example, women going through menopause sometimes report “brain fog” that can mimic early dementia. Anxiety, depression, or sleep disorders can also impair memory and concentration — but these causes are treatable.

Chronic stress also plays a significant role in cognitive performance. When the body remains in a high-alert state, elevated cortisol levels can impact the hippocampus, the part of the brain responsible for forming new memories. This often manifests as forgetfulness or an inability to focus, which patients may mistake for the early stages of a neurodegenerative disease.

Furthermore, metabolic issues such as thyroid dysfunction are frequent culprits of mental slowing. An underactive thyroid can cause "pseudodementia," characterized by sluggish thinking and a depressed mood. Because these symptoms are often resolved through hormone replacement therapy or lifestyle adjustments, a comprehensive blood panel is a vital step in any cognitive evaluation.

Early intervention remains the most effective strategy. While the fear of an Alzheimer’s diagnosis is significant, many people discover that their memory struggles are linked to manageable health conditions. Addressing these underlying factors not only clears the "fog" but also improves long-term brain resilience and overall quality of life.

Why Planning Still Matters

Even if your loved one’s symptoms turn out to be temporary, the reality is that longevity increases everyone’s risk of eventually needing long-term care. Dementia or not, aging often leads to chronic illnesses, frailty, or mobility issues. With long-term care services, including memory care, not covered by Medicare, the impact can create a family crisis. 

The financial stakes are enormous: the LTC News survey of long-term care costs shows that assisted living costs average over $60,000 per year nationally when you include surcharges, memory care even more, and nursing home care often exceeds $120,000 annually. While in-home caregivers can be less, those individuals needing supervision generally require more extended care, which increases those costs. These costs can adversely impact income and lifestyle, draining retirement savings and burdening your spouse or children.

Families need to plan ahead. Long-Term Care Insurance is the only way to guarantee tax-free funds for quality care at home or in a facility without spending down assets.” —Jesse Slome, director of the American Association for Long-Term Care Insurance.

Tips for Smart Planning

• Act before retirement: Premiums are lower, and you’re more likely to medically qualify in your 40s or 50s. Yet, premiums and underwriting rules vary dramatically between insurance companies. Seek help from a qualified Long-Term Care Insurance specialist to get accurate quotes on LTC Insurance options.
• Work with a true specialist: Choose someone representing multiple top-rated insurers. When you seek accurate quotes for Long-Term Care Insurance, you can rely on LTC News Trusted LTC Insurance Specialists. These LTC News trusted partners are professionals who are screened by LTC News and hold the esteemed CLTC designation, are endorsed by the American Association for Long-Term Care Insurance (AALTCI), and come highly recommended as Ramsey Trusted Pros by financial expert Dave Ramsey’s organization (Ramsey Solutions) - Quotes From Trusted Long-Term Care Insurance Specialists.
• Consider partnership LTC policies: These can help you shelter your assets no matter how long and costly your long-term care event.

Prepare for the Possibility of Memory Issues with Aging

Alzheimer’s and other dementias remain a massive challenge for American families, but don’t jump to conclusions if your parent or partner shows signs of cognitive decline. A thorough medical evaluation can sometimes uncover treatable causes. Still, you should prepare for the possibility of needing care later in life. Long-Term Care Insurance can help you safeguard your income, protect your savings, and ensure your loved ones aren’t left with impossible decisions.

Remember, while some cognitive changes can be reversed, the rising prevalence of Alzheimer’s and other forms of dementia makes proactive planning essential. Experts suggest that waiting for a crisis to occur often limits a family’s options and increases the emotional and financial strain on caregivers. By addressing the logistical and financial aspects of aging early, families can ensure that a loved one receives high-quality care in the setting of their choice.

A critical component of this preparation is understanding the high cost of professional care. Because traditional health insurance and Medicare do not cover long-term "custodial" care—the type of assistance required for those with memory impairment—many families are forced to pay out of pocket. Long-term care insurance can provide a dedicated funding source for home care, assisted living, or memory care facilities, but these policies must be secured while an individual is still relatively healthy and meets underwriting requirements.

Beyond financial planning, establishing legal safeguards is vital. Executing a durable power of attorney and a healthcare proxy allows an individual to designate a trusted person to make decisions on their behalf if they become incapacitated. Having these documents in place ensures that a transition to higher levels of care is handled according to the individual’s previously stated wishes, rather than through a complicated and costly court-supervised guardianship.

Finally, families should familiarize themselves with available resources before they are needed. Researching local memory care specialists, support groups, and the LTC News Caregiver Directory can provide a w way to find caregivers and long-term care faciltiies when a loved one needs care now, or in the future.

You need a roadmap for the future. Understanding the 56% probability that an older adult over 65 will eventually require some form of long-term care helps shift the conversation in your mind from fear to empowerment, allowing you and families to focus on maintaining quality of life regardless of a diagnosis. Acting and preparing before your health or mind declines will help you ensure you will have access to your choice of quality extended care, safeguarding your income and assets from the rising cost of memory care and other long-term care servcies.
