Navigating Memory Disorders: Classification, Differences between Dementia and Alzheimer’s Disease, and the Implications for Joe Biden’s Forgetfulness


Joe Biden’s memory lapses: What do they reveal?

In an interview with Prof. Eli Mizrahi, an expert in geriatrics and psychogeriatrics from the Faculty of Medicine at Tel Aviv University, we learned that memory disorders can be classified into two categories: benign and mild. The first type, known as a “remembering” disorder, is characterized by the presence of information in the brain but difficulty retrieving it due to slow nerve transmission as we age. Approximately one or two percent of those who suffer from this disorder will develop dementia later in life.

On the other hand, the second type is a mild memory disorder called “Age Associated Memory Impairment.” This condition involves a decrease in short-term memory and can lead to changes in brain tissue similar to those seen in people with Alzheimer’s disease. About 12% of those who experience this mild memory disorder will develop dementia or Alzheimer’s.

Prof. Mizrahi explains the difference between dementia and Alzheimer’s disease, noting that dementia is a decline in mental capacity affecting day-to-day functioning. Alzheimer’s disease is the underlying cause of about 60% of all dementia cases and initially affects higher functions such as driving and decision-making before progressing to impair basic actions such as bathing and eating.

Regarding Joe Biden’s forgetfulness during press conferences, Prof. Mizrahi notes that while it does not conclusively indicate a cognitive problem, there is room for concern based on his confusion with names and topics that he should have mastered as president. This type of forgetfulness can be a red flag for cognitive decline, similar to what was observed in President Reagan, who also suffered from Alzheimer’s disease. Prof. Mizrahi suggests further assessment based on Biden’s day-to-day cognitive functioning and feedback from his family and staff are necessary to make a proper evaluation.

In conclusion, memory disorders can be divided into benign and mild types; the latter can lead to cognitive decline if left untreated or ignored. It is essential to monitor individuals closely for signs of cognitive decline, especially if they are older adults or have pre-existing conditions such as Alzheimer’s disease. Early detection and intervention can significantly improve quality of life for both patients and their loved ones.
