“Exceptions confirm the rule”, this proverb could be applied to a family
that suffers from a unique memory deficit: at least four generations struggle
to assign words to concepts and meaning, which results in problems to memorize
word lists or even stories they were just told. Although the family in question seems to be
the only one with this specific trait, research could bring results that
explain language development in general. Tests have shown, that members of this
family have verbal intelligence like everybody else and non-verbal intelligence
that is even above average, which contradicts some of the family member’s
self-perception of being stupid. What makes their brains different from the ones
of the control group is the comparatively little amount of “neurons and glial
cells” – the so-called “grey matter” in a brain area that is “linked to
processing word meaning”. This abnormality might be caused by one single gene,
which is currently searched for by geneticist Simon Fisher and psychiatrist
David Skuse. Yet, although these findings could help us to better understand our brains, it probably comes a little late for the family.
