2. According to a new study of
Wisconsin University
Young primates with Have decreased activity
highly anxious of specific genes within
temperaments the amygdala
3. The genes involved play a major role in forming
the brain connections needed for learning about
fears.
4. The function of genes that promote learning
and plasticity occurs in the amygdala
5. Anxious individuals tended to have decreased
expression of a gene called neurotrophic tyrosine
kinase, receptor, type 3 (NTRK3)
The risk to develop anxiety and depression may
be related to the underactivity of particular
genes in the developing amygdala
6. The study
helps
Support the need for
early intervention in
children identified as
excessively shy and
anxious.
Point a way to better
treatments to decrease
the likelihood of children
developing more severe
psychiatric problems
7. Therapy Neuronetics transcranial magnetic
stimulation (TMS) can relieve symptoms of
depression and has little or no side effects on
the sleep disorder.
8. The Major Depressive Disorder affects approximately 14.8
million, or about 6.7 percent of American adults in a given
year, according to the National Institute of Mental Health
It's the leading cause of disability in ages 15 to 44
9. The finding resulted from an analysis of a
study of 301 patients at 23 sites
comparing the anti-depressive effects of the Neuronetics
Transcranial Magnetic Stimulation Therapy System (TMS)
treatment in patients resistant to antidepressant medications
10. The findings, published in the journal Biological Psychiatry in
2007,affirmed TMS's effectiveness in depression
Sleep problems are a common side effect of major
antidepressants: some drugs sedate patients while others
stimulate them and increase insomnia.
11. Insomnia occurs in 50-90 percent of patients with
major depressive disorder. Other depressed patients
complain they sleep too much
The good news is that TMS does not contribute
to insomnia or oversleeping.
12. TMS targets the prefrontal cortex of the brain, involved in
mood regulation as well as other higher-order functions like
planning, evaluating and decision-making
In this procedure, patients sit in a recliner
and receive brief pulses of a MRI strength
magnet held against the front of the head
The magnetic energy of TMS causes the brain cells closest
to the surface of the brain to increase their activity which in
turn influences the activity of the brain as a whole.
13. DEPRESSION
Memory storage
In depression, the brain becomes less plastic
and adaptable, and therefore less able to Such as
perform certain tasks.
Researchers at Karolinska Institute have traced less brain plasticity
reduced functionality in their support cells, and we believe that learning
more about these cells may pave the way for radical new treatments for
depression.
14. It has been possible the cure of
memory dysfunction in depressed is a substance secreted by
rats giving them dose of D-serine astrocytes, which are
support cells for brain
neurons
Their memories were
checked by repeatedly
The rats are placed through the two exposed to different objects
tests to confirm that they had
symptoms that are also characteristic
of human depression. Then evaluated their level of
apathy, releasing the rats in a
container with water and
observing if or not trying to
get out.
15. The synaptic activity in the hippocampus
of rats depressed is much greater than
the healthy rats
but
the level of plasticity of rats with
depression is less than the healthy
rats
However by supplying D-serine to the rat brain plasticity with depression
improvement.
Is expected that advances in the studies will
lead to new treatments for depression
