Parkinson’s disease and Sleep.

May 12, 2009

There could be a connection between Parkinson’s disease and the sleep process.  The symptoms of Parkinson’s disease seem to have a similarity to the physical processes that occur when we are in a deep sleep.  When  we are asleep our gastrointestinal tract slows down. Our urinary system has dulled signals. Our need for swallowing decreases and the signals from our brains that tell our arms and legs what to do changes. Our need to have or control our facial impulses diminish. I think it is related in a basic way to Schizophrenia only because it occurs in the same area of the brain that is in control while we are asleep. Parkinson’s  symptoms occur due to a faulty disconnection from the sleep area of the brain just like a lamp that is only partially plugged into a wall getting flickering symptoms.

Schizophrenics have a disconnection difficulty with the mental aspects of sleep and Parkinson’s  effected people have a disconnection problem with the physical aspects of sleep.

* What I think is interesting, is how Parkinsons symptoms seem to be the same as the physical

changes that happen to us during deep sleep.

ie..we dream we are running, but our legs don’t move.

And our gastrointestinal system slows down.

Our urinary system alters.

Our facial expressions while dreaming are flat.

 

And so Parkinsons and Schizophrenia both seem to me, to be

sleep disorders. Schizophrenia is a dream state while awake, and

Parkinsons is a physical sleep state while awake.


Older antipsychotic medication versus mordern antipsychotic medication and Dopamine re uptake versus Dopamine blocking.

March 27, 2008

Older anti-psychotics work very well for acutely and floridly psychotic people. Modern anti-psychotics seem to be objectively very poor in my opinion at treating acute psychosis. This could be due to the mechanisms of action.

If the process of psychosis involves the flooding of the brain with Dopamine, perhaps the excess Dopamine is being picked up by Dopamine receptors from dormant neighbouring, neuron dopamine receptors. The old fashioned anti-psychotics block re-uptake, therefore preventing the Dopamine from entering dormant neurons. Modern antipsychotics block the Dopamine to slow the flow of Dopamine into the synapse. If there is already a flooded overload of Dopamine, then there is little immediate benefit to be had from Modern Antipsychotics.

Modern anti psychotics probably have a better chance of achieving results in prodromal or mild/emerging psychosis or as a preventative measure in a schizophrenic who is experiencing a remission of symptoms.

Another take is that newer antipsychotics are just not sedating enough and so they don’t increase sleep or REM sleep.  Modern antipsychotics aren’t as sedating.


Emotional Memory Tools, REM Sleep and Psychosis

August 20, 2007

We probably establish pathways, mechanisms or tools for avoiding depression, psychosis, personality disorders, autism and enhancing intelligence inside our brains before we are born; these tools can be enhanced or depleted as we age. Biological susceptibility to depression, psychosis, personality disorders, schizophrenia and autism could be counteracted by strengthening these neurological tools.

A child probably creates emotional memory foundations or tools with the help of the hippocampus, and these foundations serve as protection from mental illness. For example, when frightened a small child might curl up into a fetal position. The fetal position (a tool used during times of stress) is stored in the brain by the hippocampus as a position that produces calming emotions. This position helps the brain to reconnect with pathways that were linked to the sensation of calm felt as a fetus.

It is well known that babies respond well to being wrapped snugly in a way that mimics how they might have felt in the womb. This calming of the child results in lowering cortisol responses which allow the brain to function at a higher level. Stress produces cortisol which may attach to steroid binding sites in the brain, particularly in the hippocampus, which plays a major role in memory.

If a child who is frightened is provided with a new calming experience, verbal or non verbal, a new emotional memory foundation will be learned and stored in the brain with the help of the hippocampus. The new emotional memory foundation is possibly cemented at night during REM sleep.

Towards adolescence the rate of emotional foundations learned from positive human experiences decreases as the comforting from family decreases, so adolescents become more reliant on drawing from their stored emotional memory reserves during times of stress.  Stress and anxiety have been proven to affect memory and make concentration difficult. The emotional memory tools possibly decrease stress, decrease cortisol levels, increase serotonin levels and allows the brain to function with more perceived clarity. These emotional memory tools  are possibly accessed during REM sleep.

For example, healthy adolescents become increasingly emotionally independent from their parents. During sleep, they have dreams that reflect the strong emotions felt during the day. Throughout the dreaming process, the brain accesses emotional tools, for example the soothing feeling from a memory of being physically comforted, laughing or being verbally reassured. This results in a decrease of ‘real’ stress, decreases cortisol, increases serotonin and the adolescent wakes up feeling refreshed and happier.

Individuals likely to experience recurring depression or mental illness have insufficient emotionally soothing memories due to negative experiences, structural neurological deficiencies, lack of sleep, or lack of REM. This limits the storage of positive emotional tools or leads to difficulty accessing stored tools at night.

It is important for parents to let their children experience a range of emotions with positive outcomes as a child. Children surrounded by negativity store destructive memories often resulting in chronic dysthymia and depression. Skewed and maladaptive emotionally soothing memories may encourage personality disorders. If emotionally stored tools are based only on physical/non verbal events, addictive type personalities may result.

Schizophrenics may not be able to access a store of emotionally soothing memories due to poorly functioning neurological systems. This interferes with the formation of emotional tools, resulting in psychosis.

People who suffer from post traumatic stress may experience recurrent nightmares because their brains are unable to find stored memories to match and combat their extreme stressor.

Adults who had anxious parents go to sleep with a calm feeling which gives way to a store of anxiety-laden emotional memory during sleep. As an adult, they wake up with increased anxiety. The same pattern is exhibited with people who had overly critical and negative parents, perhaps culminating in depression.

Infants utilize emotional storage. They register “happy faces”, “sad faces” etc. They also store calming memories during periods of closeness, cuddling and breast feeding. A child completely devoid of human contact will become autistic. They intellectualize all of their soothing.

Autism can also result from infection/physical damage to the hippocampus which possibly hinders adequate laying down of emotional memories. Autistic kids who self soothe with rocking may have this emotionally memory tool stored before birth but they cannot build on this. Head banging may relieve some of the physical discomfort caused by excesses in cortisol and stimulate the release of serotonin.

Allowing children to sort through emotionally stressful issues all by themselves may promote or enhance intellectual ability by stimulating new neural pathways. They can create their own emotional tools using logic and reason, although this should not be relied upon as a sole basis for emotional foundation. An over-reliance on intellectual soothing can posssibly lead to emotional disconnection, culminating in Aspergers-like symptoms.
