Very late-onset behavioral variant frontotemporal dementia

Area of Science:

• Neurology
• Neuroscience
• Geriatric Medicine

Background:

• Frontotemporal lobar degeneration (FTLD) encompasses a group of progressive neurodegenerative disorders.
• Recent advancements have improved understanding of FTLD, particularly genetically determined subtypes.
• Behavioral variant frontotemporal dementia (bvFTD) is a common clinical presentation of FTLD.

Observation:

• A case report of a patient in her nineties diagnosed with bvFTD.
• The diagnosis was made during hospital admission for a ground-level fall.
• This presentation occurred in the context of late-onset dementia.

Findings:

• The case illustrates that bvFTD can manifest and be diagnosed in very late life.
• Late-onset dementia may present with behavioral changes characteristic of bvFTD.
• The patient's presentation highlights the diagnostic challenges in elderly individuals.

Implications:

• Increased clinical awareness of bvFTD is crucial for accurate diagnosis in older adults.
• This case underscores the importance of considering FTLD in the differential diagnosis of late-onset cognitive decline.
• Recognizing bvFTD in late life can lead to more appropriate patient management and care planning.
