Women Reportedly Facing Rising Early-Onset Dementia

As we grow older, the fears that once haunted our childhood—like imaginary monsters in the dark—are quickly replaced by adult concerns. For many Nigerians and West Africans, worries about rising cost of living, making house rent, fuel price hikes, and the reality of health challenges like dementia are front and centre. Data from international studies suggest that women, in particular, are more likely to express anxiety about developing dementia. Reports indicate that even minor memory slip-ups can spark significant worry about early-onset dementia. But what is the real prevalence of early-onset dementia among women in Nigeria, and more importantly, what practical steps can you take to protect yourself or your loved ones in our unique African context? Let’s explore current research, share local insights, and discuss meaningful actions.

Dementia Among Women: The Numbers in Context

According to the World Health Organization (WHO), the global number of people living with dementia is projected to double every 20 years, reaching an estimated 78 million by 2030. In Nigeria and other African nations, this issue is particularly pressing as women account for a large share of cases. The situation is influenced by a range of factors: women’s higher average life expectancy as well as hormonal and lifestyle changes, particularly during menopause, make them more vulnerable to cognitive decline.

Concerns about early-onset dementia—defined as dementia that presents before age 65—are rising both globally and across the continent. A cohort analysis published in Translational Psychiatry highlights that early-onset cases are growing fast, especially in low- to middle-income regions like Nigeria, Ghana, and other West African countries. Socioeconomic challenges, limited healthcare resources, and widespread health disparities often mean that detection and management lag behind global best practices. This underlines the urgent need for targeted interventions in Africa, where awareness and support systems are still evolving.

Why Do Women Face Higher Dementia Risks?

Young-onset dementia—when symptoms develop before age 65—hits women particularly hard in Nigeria and across Africa. While longevity plays a role in explaining why more women experience dementia, several other factors combine to tilt the odds: hormonal shifts (especially the drop in protective oestrogen during menopause), chronic social stress, and the traditional expectation for women to act as family caregivers all play a part. Many West African women balance a host of responsibilities—running homes, supporting extended families, and trying to build careers—which can increase stress and limit the time and resources available for self-care and medical checkups.

The biological side of the story suggests that falling oestrogen during menopause may reduce protection for brain cells, potentially accelerating the disease process. Recent international research, including a 2024 study, revealed that conditions like preeclampsia—high blood pressure during pregnancy—significantly raise dementia risks later in life for women, pointing to the importance of monitoring health across all life stages. In Nigeria, where maternal health complications still occur at high rates, this is a critical wake-up call for improved women’s health services and education.

Spotting Dementia Early: Key Symptoms to Watch For

Dementia rarely appears suddenly—it unfolds gradually, marked by early and often subtle shifts in memory, thinking, and behaviour. Nigerians should be alert to common warning signs, including:

Persistent memory loss that interferes with everyday activities
Challenges remembering how to perform routine tasks
Difficulty with speech or writing
Losing track of dates, time, or familiar places
Problems interpreting visual information
Frequent misplacement of items and inability to retrace steps
Poor judgment in decision-making
Mood swings, increased irritability, or withdrawal
Reduced interest in work, social, or religious activities
Trouble solving problems or making plans
Lack of coordination or physical control
Ongoing confusion and disorientation

In many parts of Nigeria and Ghana, misinterpreting these signs as “just part of getting older” is alarmingly common, and it can delay intervention. According to a 2023 study published in Dementia (London), many patients face late diagnosis due to several challenges:

Lack of dedicated dementia services at local clinics and health centres
Varied levels of training among healthcare professionals
Healthcare workers sometimes believing that “nothing can be done for dementia”
Dismissing dementia symptoms in younger patients

But it’s not just the medical system—many families and individuals ignore early symptoms, blaming them on stress, ageing, or spiritual causes. Neurologist Dr. Chika Ugochukwu, practicing in Enugu, emphasises: “Persistent forgetfulness or thinking problems in adults, even in their 40s or 50s, should not be brushed aside. Early assessment by a trained physician or neurologist is essential to improve outcomes.”

How Can Dementia Be Prevented? Local Perspectives and Evidence

Experts now believe that up to 45% of dementia cases could be prevented by addressing a set of 14 changeable risk factors at different life stages. In Nigeria and much of Africa, education about these risks remains limited, but awareness is slowly growing. While some risk aspects—like early school dropout linked to economic pressures—can be hard to address, others are much more modifiable.

Major risk factors in West African urban and rural communities include isolation, depression, high blood pressure, obesity, and diabetes—all on the rise alongside lifestyle changes and urbanisation. According to Dr. Amina Abubakar, a Lagos-based public health expert, “The increasing burden of hypertension, diabetes, and stroke in Nigeria and Ghana is deeply worrisome because they’re all strongly tied to dementia risk. Community-based education and screening could help reverse these trends.”

Moreover, Dr. Abubakar notes that protecting your brain isn’t just about ‘old age prevention’—it’s about adopting healthy habits in your 30s, 40s, and 50s, as those years set the trajectory for cognitive health later. Habits like smoking, poor sleep, lack of physical activity, and heavy alcohol use damage brain tissue over decades. According to international and local research, up to four in ten dementia cases could potentially be prevented or delayed with these lifestyle changes.

Brain-Boosting Habits Nigerians Should Start Now

1. Improve Your Diet with Local Flavours

A healthy diet isn’t limited to expensive imported “superfoods.” Nigerians can go far by prioritising fresh fruits, leafy vegetables, beans, lean proteins like fish, and traditional whole grains (e.g., guinea corn, millet). Nutritionists in Lagos and Abuja suggest that swapping out processed foods for home-cooked options like okra, ugu, and up-country fish stew can lower your risk for diabetes and hypertension—two major dementia risk factors. According to Dr. Francis, dementia “is not an unavoidable part of ageing, but a result of decades-long exposure to risks we can often control.”

2. Control and Prevent Lifestyle Diseases

Conditions like high blood pressure, diabetes, and high cholesterol can weaken the brain over time. Local doctors often stress regular screenings, medication adherence, and healthy living. Cutting down on alcohol, avoiding smoking, and tackling excess stress—including from family obligations—can help protect your cognitive future. Dr. Atukpa Oladipo, a healthcare consultant in Abuja, adds, “Many people avoid hospitals due to cost or fear, but early checks save money, suffering, and lives down the line.”

3. Be Physically Active—No Equipment Needed

You don’t need a fancy gym membership to support brain health. Simple activities like brisk walking to the market, dancing at church, or even traditional games like ayo (mancala) keep both mind and body engaged. Set achievable goals: join a local walking group, sign up for a fun run, or even try at-home exercise routines.

4. Challenge Your Brain Daily

Continued learning and mental activity help build “cognitive reserve,” making the brain more resilient to disease. Whether it’s reading, learning a new skill, playing local games that require strategy, or attending community meetings, staying mentally engaged is key. According to Abuja-based psychologist Mrs. Nkiru Odion, “Even reading newspapers in different languages or debating football tactics with friends keeps the mind sharp.”

Isolation can speed up mental decline. Regular family meet-ups, involvement in religious or community activities, and maintaining friendships all protect cognitive function. With smartphones and apps, even those living far from loved ones can stay in touch, share stories, and join discussions that stimulate memory and reasoning.

It’s clear that dementia is not just an “oyinbo” dilemma or a concern for the affluent—it’s an urgent issue for Nigerian and West African women and families. By raising awareness, promoting community dialogue, and taking practical, culturally relevant steps, we can fight back against this complex disease.
