Dr. Rhonda Voskuhl: Brain games fail against midlife fog

Neurologists Warn Generic Brain Games Fail to Resolve Midlife Mental Fog

Generic brain exercises like Sudoku and number puzzles do not fix the specific verbal memory slowdowns caused by midlife hormone shifts, neurologists warned at the Livelong Women’s Health Summit in New York City last September, Fox News reported. Dr. Rhonda Voskuhl, a neurology professor at UCLA and co-founder of Cleopatra RX in Los Angeles, stated that cognitive exercises must target exact functional deficits rather than general logic.

Verbal Memory and Processing Speed Deficits During Perimenopause

Midlife mental fog driven by estrogen loss leaves basic logic and overall IQ intact while specifically degrading verbal memory and processing speed. Voskuhl explained that drops in estrogen do not cause global brain atrophy, but MRI scans reveal functional connection issues and tissue shrinkage in the hippocampus, the brain’s primary memory center. This localized decline impairs word retrieval and rapid thinking rather than basic encoding or storage.

The distinction separates how the brain stores information from how it extracts it. Mental fog affects retrieval, meaning names and words remain securely stored in memory, but the brain’s search mechanism operates too slowly to access them immediately.

Targeted Speed and Word Drills for Cognitive Training

Effective cognitive training requires drills focused on rapid word recall and processing speed rather than static math puzzles. Voskuhl recommended specific exercises designed to force quick thinking:

• Timed category drills requiring individuals to list as many food or animal items as possible within a 60-second window.
• Speed reading exercises paired with immediate two- or three-sentence verbal summaries of the text.
• Rapid recall flashcard drills that demand instant identification of objects or people without pauses.

Instead of relying on generic mobile applications, patients should evaluate their own daily cognitive stumbling blocks and select games that challenge those specific weaknesses. Voskuhl noted that individuals recognize the mental tasks they once performed easily but now find difficult, providing a baseline for targeted practice.

Frequently Asked Questions About Brain Fog and Cognitive Exercises

Do Sudoku and crossword puzzles help improve memory loss?

No. Sudoku and number puzzles primarily exercise math logic and general reasoning, which leaves verbal memory and word-recall difficulties unaddressed, according to Dr. Rhonda Voskuhl.

What specific areas of the brain are impacted by midlife estrogen drops?

Estrogen loss specifically impacts the hippocampus, leading to functional connection issues and localized changes that affect verbal memory and processing speed, while leaving overall intelligence intact.

What is the difference between encoding and retrieval in memory?

Encoding is how the brain takes in and stores new information, while retrieval is the process of pulling that stored information back up when needed. Brain fog typically disrupts retrieval rather than encoding.
