7. The Symptom Overlap: A Cloaked Deceiver
Pseudodementia’s hallmark feature is its ability to mimic the cognitive symptoms of true dementia. However, a crucial point of distinction lies in the sequence and presentation of these symptoms. In true dementia, cognitive symptoms precede mood changes, while in pseudodementia, mood symptoms often precede cognitive decline.
In the early stages of true dementia, cognitive symptoms such as memory loss, difficulty with language, and problems with decision-making are often the first signs. As the disease progresses, individuals may develop mood symptoms such as depression or anxiety.
On the other hand, in pseudodementia, the order of symptom presentation is often reversed. Mood symptoms, such as depression or anxiety, usually emerge first, followed by cognitive changes.
Understanding this distinct symptom progression is vital to correctly diagnose pseudodementia and distinguish it from true dementia. It’s a subtle clue that can have profound implications for diagnosis and treatment. (7)
