fibromyalgia
what treatments can be used for fibromyalgia?
- pain meds and muscle relaxants
- antidepressants and anti epileptic drugs
is there a cure for fibromyalgia?
no since the cause is unknown
what is the implication of a PT and OT on fibromyalgia?
PT: flexibility and strength
OT: ADLs with minimal stress on body
what are life changes that may help reduce pain in patients with fibromyalgia?
meditation, sleep, exercise, reduced caffeine, smoking an alcohol
what are the different types of strokes?
- ischemic (thromboic and embolic) where a clot is formed
- hemorrhagic where a vessel breaks
what happens in the case of a stoke to the brain tissue?
lack of o2 and nutrients leads to its death
who is most at risk of stoke?
men
>55
indigenous, african & south asian
what are risk factors associated to stoke?
HTN Smoking WHR sedentary diabetic
what does FAST stand for?
primary signs of stoke Face drooping arm weakness slurred speach time
what are other signs associated with stoke?
- weakness on one side of the body
- blurred or double vision
- headaches
what are some common impairments after stoke?
depression & mood changes
low energy
cognitive deficits
dysphagia
how is stoke diagnosed?
using CT/MRI to identify location and type
what are the common treatments for stoke?
ischemic: tissue plasminogen ~4.5H after stoke to break down the clot or surgical removal via stent clipping
hemorrhagic: reduce bleeding and BP by clipping, endovascular embolization and high beam radiation
what is often used after stoke to reduce spasticity?
balcofen or
FES
what is the role of PT/OT for stoke?
PT: recover motor losses, endurance, ROM & strength
OT: fine motor skills, adaptive techniques & technologies
what is affected by addiction?
mesolimbic dopamine pathway by increasing the [dopamine] in the synapses which induces the production of cAMP and increases CREB production.
what is the result on dopamine caused by addiction?
natural endogenous dopamine production is reduced and hence increases the body’s demand for with
what cortical organs are involved in addiction?
amygdala
hippocampus
cortex
who is most at risk of addiction? of intoxication?
addiciton: men
intoxication: women
what are the common risk factors associated to addiciton?
poor familial status peer pressure easy access to drugs impulsive personality mental health issue abuse
what are signs and symptoms often associated to addiction?
craving
tolerance
nelect of responsibilities
development of mental illnesses
what are the common symptoms associated to withdrawal?
sweating vomiting and nausea increased HR irritability hallucinations
what are the common treatments used for addiciton?
self help groups as they are empowering
medications to help prevent withdrawl
CBT
what is alzheimer?
neurogenerative disease which causes cortical cell death
what causes alzheimer?
- development of amyloid plate which disrupt synaptic communication, and increase cell death and excitotoxicity
- neurofibrillary tangles which impede communication
what NTs seem to be decreased in Alzheimer?
NE
ACh
serotonin
what part of the brain shows atrophy in Alzheimer
medial temporal lobe and hippocampus
what causes Alzheimer?
unknown cause
what are the risk factors associated to Alzheimer
- genetic (APOE 4 or trisomy 21 gene)
- environmental
- lifestyle
who is most at risk of Alzheimer
women
> 60
african americans, causians , and hispanics
what symptoms are associated with mild AD?
short term memory loss
what symptoms are associated with moderate AD?
short term memory loss inappropriate behavior redundancy apraxias damage to cortical areas involved in reasoning, conciousness, language and information processing
what symptoms are associated with severe AD?
brain atrophy communciation impairments dysphagia seizures gait abnormalities bladder and bowel impairments
how can Alzheimer be diagnosed?
no explicit test
use medical history, imaging techniques, lab tests and neurological exams
what medication can be given to treat Alzheimer?
-cholinesterase inhibitor which allows to maintain ACh and thus increase communication between cells
anti-psychotic drugs
how can PT OT help patients with Alzheimer?
-improve gait and balance and promote PA and cognitive health
educate patient and caregiver on AD and help with communication strategies
what is Parkinsons disease?
neurological motor disorder that is due to the loss of dopaminergic neurons in the substancia nigra
what is the role of lewy body formation in PD?
Believed to prevent neuronal functionning
when is PD generally diagnosed?
~60-65 years old
what is the greatest risk factor associated to PD?
age
who is most at risk of PD?
men
western countries
what are some risk factors associated to PD?
genetics
environmental (pesticides)
what is the effect of coffee and cigarets on PD?
recuces risk, considered to be negative risk factors

- dysphagia, incontinence/cosntripation
- dementia
- depression
- day time sleepiness
-parkinson disease
what are the most common treatments for pd?
- Levodopa which increases Dopamine availibility
- deep brain stimulation which inhibits the inhiitory pathway by inhibiting the STN and allows to take smaller medications
what is paranoid schizophrenia?
mental disorder characterized by debilitating symptoms such as hallucinations, dellusions and constant suspiciousness
