It was heartbreaking for Mark Hatzer to realize that his mother, Sylvia, an 82-year-old woman living with dementia, could no longer recognize her own son. Having already lost his father, the thought of losing his mother as well was devastating. As Sylvia’s condition worsened, she was admitted to North Manchester General Hospital for her own safety.
Her decline had been gradual at first. In 2015, Sylvia began forgetting appointments and birthdays. At the time, this seemed like a normal part of aging. However, in December 2016, doctors diagnosed her with Alzheimer’s disease, and Mark soon noticed a rapid deterioration in her mental state.
Occasional memory lapses were understandable. Sylvia even once accused hospital staff of kidnapping her and called the police—an episode Mark could forgive. But when she reached a point where she no longer recognized him, he described it as “the lowest point” of his life.
A Turning Point
After spending nearly two months in the hospital, Sylvia was finally discharged. While she was no longer in immediate danger, she continued to show many common signs of dementia, including:
- Short-term memory loss
- Increased confusion
- Difficulty concentrating
- Changes in personality or behavior
- Withdrawal, apathy, or low mood
- Trouble completing simple daily tasks
At that point, the Hatzer family made a decision that would significantly change Sylvia’s trajectory.
Instead of relying solely on medication, they chose to focus on lifestyle-based approaches, particularly nutrition.
“When she left the hospital, instead of prescribed medication, we thought we’d try an alternative approach,” Mark explained. “In Mediterranean countries, dementia appears far less common, and diet seems to play a major role.”
They emphasized foods traditionally associated with brain health, such as oily fish, berries, walnuts, and Brazil nuts—many of which are rich in nutrients known to support cognitive function.
The Mediterranean Diet and Brain Health
For years, researchers have studied dietary patterns in Mediterranean regions such as Italy, Spain, Greece, and southern France. These diets are typically rich in fruits, vegetables, legumes, whole grains, olive oil, and fish, with lower intakes of sugar, processed foods, and saturated fats.
According to the Alzheimer’s Society, Mediterranean-style diets emphasize plant-based foods, moderate amounts of dairy and fish, and minimal red meat—an approach increasingly linked to better cognitive health.
One key component of this diet is omega-3 fatty acids, especially EPA and DHA, which are found in fatty fish. Scientific research suggests that omega-3s support neuronal cell structure, help regulate inflammation in the brain, and may play a role in slowing age-related cognitive decline.
Scientific Evidence Supporting Mediterranean Diets
Growing evidence supports the potential cognitive benefits of Mediterranean-style eating patterns.
At the 2017 Alzheimer’s Association International Conference, researchers reported that adults who closely followed a Mediterranean or MIND diet had a 30–35% lower risk of cognitive impairment, even after accounting for factors such as age, education, smoking, physical activity, and chronic disease.
Earlier research supports these findings as well. A 2013 systematic review published in Epidemiology found that stronger adherence to a Mediterranean diet was associated with slower cognitive decline and a reduced risk of developing Alzheimer’s disease. A later 2016 review in Advances in Nutrition echoed similar conclusions, noting consistent links between Mediterranean diets and better cognitive performance, while emphasizing the need for further research.
Lifestyle Changes That Supported Improvement
Diet was only one part of Sylvia’s routine. According to Mark, three key lifestyle changes contributed to her noticeable improvement:
- Dietary changes focused on nutrient-dense, brain-supportive foods
- Cognitive stimulation, including crosswords, jigsaw puzzles, and social engagement
- Physical activity, using a seated pedaling device to stay active safely
Over time, these changes made a difference.
“It wasn’t an overnight miracle,” Mark said. “But after a couple of months, she began remembering birthdays again. She became more alert, more engaged—more like her old self.”
He emphasized that a diagnosis does not have to signal the end of quality life.
“You’ll have good days and bad days,” he said, “but it doesn’t have to be the end.”
A Message of Hope
Sylvia’s experience highlights the potential impact of nutrition, mental stimulation, and movement at any age. While no single approach works for everyone, small, consistent lifestyle changes may help support brain health and overall well-being.
If meaningful improvements are possible even later in life, it’s never too early—or too late—to start caring for your brain.
