The average age of
frontotemporal dementia onset is much younger than that of the
Alzheimer's disease. Behavioral disturbances occur at the early stage of
frontotemporal dementia, and social dysfunction and
personality deterioration may ensue. For this reason, it may be misdiagnosed as other
psychiatric disorders. Therefore, more careful
observation and concern is required for proper
diagnosis. This
report is about the case of a
patient who had been misdiagnosed of disorders like
schizotypal personality disorder,
schizophrenia,
obsessive compulsive disorder etc., and therefore have been treated for those. We reviewed this case based on the data of neuropsychiatric
history,
family history,
neuropsychological test,
brain MRI, and
SPECT, and considered this case as
frontotemporal dementia with
family history. This is the first
frontotemporal dementia case with
family history in
Korea, so hereafter we may discover the
gene locus associated with this case. This study can be very useful for the following
frontotemporal dementia studies in
Korea.
