Common Myths About Brain Health — And What the Science Really Says
For decades, we’ve been told that once brain cells die, they’re gone forever. That if we start losing our memory or thinking skills, it’s just “part of getting older” — and there’s nothing we can do about it.
This thinking has left millions of people feeling powerless. But here’s the truth: brain health is not fixed, and decline is not inevitable.
Myth 1: You Can’t Grow New Brain Cells
For years, scientists believed that the brain was static after childhood. But research has since proven otherwise.
Neurogenesis is the process of creating new brain cells (neurons) — and it happens throughout life, especially in the hippocampus, the part of the brain involved in memory and learning.
Factors that can boost neurogenesis include:
-
Physical activity (especially aerobic exercise)
-
Quality sleep
-
A nutrient-rich diet
-
Mental stimulation and learning new skills
-
Positive social connections
Myth 2: The Brain Can’t Rewire Itself
This is where neuroplasticity comes in — the brain’s ability to reorganise and form new connections between neurons. Neuroplasticity allows the brain to adapt after injury, learn new information, and even regain lost skills.
With the right stimulation, we can strengthen healthy brain pathways and create workarounds for damaged ones.
Myth 3: Dementia Can’t Be Reversed
Neurologist Dr Dale Bredesen has challenged this long-held belief. Through his work with patients, he’s shown that cognitive decline — even early Alzheimer’s — can be slowed, stopped, and in some cases reversed.
He calls the idea that “there’s nothing you can do” false hopelessness. His approach targets the underlying drivers of brain decline, such as inflammation, nutrient deficiencies, toxin exposure, poor circulation, and insulin resistance.
Early Warning Signs of Cognitive Decline
Don’t ignore these symptoms — they may be your brain’s early cry for help:
-
Difficulty finding words or remembering names
-
Struggling to follow conversations or instructions
-
Misplacing things more often
-
Trouble with planning or problem-solving
-
Changes in mood or personality
-
Feeling more easily confused or disoriented
The earlier you act, the more you can protect — and even improve — brain function.
The Takeaway
Your brain is capable of growth, repair, and renewal. Neurogenesis and neuroplasticity are proof that your brain health is in your hands. And pioneers like Dr Bredesen have shown that decline is not a one-way street.
If you notice early signs of change, don’t wait. The sooner you investigate possible causes — and address them — the better your chances of staying sharp for decades to come.
