Hmmmmmmmm this is indeed pretty interesting, it is especulated that MDMA
damages the dendrites (I think) of neurons that regulate mood and behavior
among other things this damage has actually seen on rats and other animals,
but never in humans, in some animals the damage was permanent, in others the
neurons had a regrowth of their dendrites of almost 100% after a year,
although the growth was chaotic
(I'll try to get sources and medical data because I'm no expert either) but
the areas that affect short term memory don't seem to be touched by MDMA
molecules, although maybe it's metabolites might affect them
I'd wish more research were done on this, it would be interesting to know if
this is a temporal or permanent effect, and if it only happens with chronic
use or with ocassional use as well.
It'd be interesting to know if this is an effect caused by MDMA or it's
analogues like MDA, MDE etc that are commonly found on E pills or even sold as
E because they have similar effects, I have heard that MDA is twice as
neurotoxic as MDMA so probably other compounds are more neurotoxic or no
neurotoxic at all.
Another theory is that this effect might be caused by the adulterants found on
E pills like amphetamines or cocaine, or on other compounds sold as E like DXM
(a powerful dissociative in higher doses, and a cough supressant in lower
doses suspected of causing Olney's lessions that might impair this skills:
Memory, especially language-related (e.g., finding words)
Understanding metaphors
Evaluating, and possibly controlling, your own behaviour
Multi-sensory thinking
Learning in new situations
Certain aspects of visual perception
With increasing doses, damage spreads beyond the posterior cingulate and
retrosplenial cortex into other areas of the brain including the hippocampus
and olfactory
areas. Damage to the olfactory tubercule would, obviously, impair one's sense
of smell. Damage to the limbic system itself could have wide-ranging
consequences
including:
Autobiographical memory
Declarative memory (as opposed to remembering skills)
Place-memory (learning and remembering your way around)
Coupling of emotions to experience
so if you've been paying attention these effects are similar to the loss of
short term memory your friends reported, it's also believed that Olney's
lessions are worse in females than in males, the reasons of this are unknown.
There's still a lot of unknowns here. Nobody has ever seen Olney's lesions in
a human brain. It could be that this damage only occurs very rarely, to people
with
underlying neurological disorders, and that most people who experience
impairment are simply suffering from neurotransmitter depletion, receptor
reregulation, or
some sort of learned phenomenon (similar perhaps to the flashbacks a small
percentage of LSD users get). That's the best case scenario.
The worst case? Everyone using dissociatives may be doing permanent damage to
their temporal and perhaps frontal lobes. This damage would be cumulative,
adding up over each experience, with heavy or extended doses doing especially
heavy damage. Unfortunately, you may not know there's anything wrong at first.
Neural networks are a lot like holograms, in that you can remove or damage
part of them and the built-in redundancy will keep things working more or less
properly
(perhaps with a bit less flexibility). Once you get to a certain threshold,
however, it gets rapidly worse. Think about it like a curve ball; from the
batter's perspective,
the ball goes in a straight line and then suddenly darts away, even though
it's really making a steady arc.
well enough of ramble here :) It'd be interesting to know if your friends
report any of these symptoms as well to know if they are female or male, and
the "brand" of E they are taking
I'm pretty interesting in knowing these things so I can know more about long
term effects from drug use so if you can give me any info please contact me.
As a final suggestion there are E testing kits that reveal if your pill has
MDMA analogues, adulterants like amphetamines or cocaine, or dextromethorphan
so I suggest that your friends use these in order to know what they are
taking, and can be safer.
