Man loses memory after visiting
dentist!
New Delhi: Medical researchers stumbled
upon a 'one of its kind' memory loss case, in which a 38-year-old otherwise fit
and healthy man lost his memory after a local anesthetic and root-canal
treatment at a dental clinic.
It has been a decade since he last made
his visit to that dental clinic but he still wakes up each day thinking it is
the day of his dental appointment. He can only remember up to 90 minutes each
day. His symptoms are similar to those depicted in movies, such as 'Memento'
and 'Groundhog Day'.
As of now, there is no evidence that
the treatment at the dentist can be blamed for his condition, but University of
Leicester psychologists have described this as a unique case to science.
Researcher Gerald Burgess said that one
of their reasons for writing up this individual's case was that they had never
seen anything like this before in their assessment clinics.
He is now appealing for people who know
of someone who might have suffered similar symptoms of memory loss, or medical
or allied health professionals working with someone like this, to contact him
in order to build up knowledge and evidence in this field of study.
He said that their experience was that
none of their colleagues in neurology, psychiatry and clinical neuropsychology
could explain this case or had seen anything like it themselves before.
The patient is fully aware of his
identity and his personality did not change, but every day the man thinks it is
the day of his dental appointment. He has to manage his life through an
electronic diary and access to prompts.
The article was published in journal Neurocase.

Eat slowly to feel fuller: Study
London: Go slow while eating your
food as people who eat slowly feel fuller and think they have eaten more than
those who eat quickly, shows research.
Previous studies have found that slow
eaters have lower Body Mass Index (BMIs) than those who gobble down their morsels.
But the reasons were not well understood.
To investigate whether how quickly we
eat influences how hungry we feel afterwards, researchers from the University
of Bristol fed volunteers Sainsbury's tomato soup through a tube into their
mouths, Daily Mail reported.
This set-up prevented the researchers
from judging visually how much soup had been eaten. The participants then had
400 ml of soup put into their mouths at two rates. One was at a fast rate of
11.8 ml for two seconds, followed by a four second pause.
The other, the slow rate, was 5.4 ml of
soup for one second followed by a 10-second pause. The volunteers were then
asked how full they felt at the end of the meal and two hours after.
Those
who took the soup more slowly said they felt fuller than the fast eaters both
immediately after the test and two hours later.
