Why dementia patients remember songs—but not faces
In this excerpt, Dr. David Perlmutter explains that Alzheimer's and related dementias often damage the brain regions responsible for facial recognition, such as the fusiform face area, more quickly than the networks that store remote autobiographical memories and musical lyrics. Because facial‑recognition circuitry is localized and vulnerable to neurodegeneration, patients may fail to recognize family members. In contrast, memories of songs, prayers, or long‑ago events are stored more diffusely across the cortex, making them more resistant to the disease’s progression. Perlmutter notes that clinicians frequently observe patients who cannot identify loved ones yet can instantly recall high‑school details or sing along when a familiar tune is started, illustrating the differing rates and patterns of brain degeneration.
