what s the pathologgy bednd altzemers
The underlying pathophysiology involves brain atrophy, amyloid plaques, neurofibrillary tangles of tau protien reduced cholinergic activity and neuroinflammation.
what are teh symptoms of lewy body dementa
visual hallucinations, delusions, REM sleep disorders and fluctuating consciousness.
parkinsonsm
frontotemporal dementa summary and presentaton
rarer type that notably affects people at a younger age (starting aged 40-60). It mainly affects the frontal and temporal lobes. The initial presentation typically involves abnormalities in behaviour, speech and language. It can be familial (inherited

- Delusosn
- Sleep dsturbalnce
- Hallucnatons
medcaton for altzemers and th drug class

Memantne - moderate to severe (bocs glutamate)
treatment for BPSSD (behavourla and psychologcal symtpms of demena)
- Risperdone or halperdol
Coping stragerges - excercse anmal therapy, dancing, lots of sunlight, reasureance, worry beads, but down on alcool and caffne n the evenng

causes of cerebral palsy
antenatal - HSV, TORCH, ntrautrine stroke,
birth - hypoxic encephalopthic ischemia, shoulder dystocia, cor prolapse, maternal heamorage
Post - menngtts, trauma, sezures, kerncterus, hypoglycemia.
causes of horners syndrome
MS
bran tuour
aprcla lung caner - pancost tuour
thyrod mass
caavernous snus thromboss
mgranses and cluster headacehs
trauma
nfecton
bleedng
what are teh ascendng tracts and where do they decussate
Spinothalamic (also known as anterolateral)
- Anterior - crude touch and pressure
- Lateral - temperature and pain
Decussate in the spinal cord - 1-2 levels about entering!!
DCML - (made up of cuneurs and gracilis)
Fine touch and proprioception
Decussate in the medulla
what are teh descendng tracts and where do they decussate
Pyramidal tracts
From the cerebral cortex, responsible or voluntary control of body musculature . Ths can furtehr be dvded nto cortcospnla and cortcobulbar .
80% of frbres decussate at the medulla.
Extrapyramidal tracts
From the bran stem carrg nvoluntatry and autonmc muscle controll sch as tone balance posture and locomoton
DOES NOT DECUSSATE.
what s teh causes of anteror cord syndrome
normally a thromboss n teh anteror spnal artery
crush njury
vascultus
sevre hypotenton
ey presentton of anteror cord syndrome
imparemtns n pain and temp senssaton (spino thalamc)
propriocepton and fine touch preserved (DCML preserved)
motor impacted
- Impairments in pain and temperature sensation, vibration and proprioception are preserved
- Bilateral Motor deficits at and below the level of injury
- flaccid paraplegia or tetraplegia below the lesion.
- Flaccidity and absent reflexes, reflexes gradually return
- Acute back pain at the level of the injury
- Temp and pain sensation alteration 2-3 segments bowel injury
Sudden loss of muscle strength and movement controll
tets and treat,ent for antior cord syndrome
- MRI - pencil like hyper intenseties
- Lumbar puncture
- Anticoagulants
- Antiplatelets and thromboprophylaxis
- Fever and glycemic control help
symptoms to menieres
triad: vertigo, hearing loss, tinnitus
feelings of fullness in ear
40-50 yrs old
can comein lusters with long breaks
imbalance
spntanous nystagmus attacks
unexpkained falls withouth LOC
imbalance
causes of menieres
excessive endolyph in teh labrynth cauing higher pressure and disruptin sensory signals - endolymphatic hydrope
treatments of menieres
prochlorperazine
antihistamines:
cyclizine
cinnarizine
promethazine
betahistine can be used as a prophylaxis
what s narcopelsy
rare condton where teh bran looses ts ablty to regulate sleep wae cyclees leadng to fallng asleep
what s cataplexy
Cataplexy is a sudden loss of muscle tone and power in response to strong emotion - it always and only occurs as part of narcolepsy .
there s a loss of orexn
key presentatons of narcolepsy
- Excessive daytime sleepiness
- Disrupted nighttime dreams
- Cataplexy - collapse causes my muscle atonia in response to sudden emotion such as laughter or surprise
- Hypangoic hallucination - dream like hallucinations
Sleep paralysis - * Excessive daytime sleepiness - Disrupted nighttime dreams
- Cataplexy - collapse causes my muscle atonia in response to sudden emotion such as laughter or surprise
- Hypangoic hallucination - dream like hallucinations
Sleep paralysis -
test for narcolepsy
polysomopraphy
multiple sleep lateny test
CSF orexin levels
treatment for narcolepsy
- Good sleep hygine
- Scheduled naps
- Monadinil, dexamphetamine, methylphenidate, and pitolisant.
- Antidepressants for calaplexy (chloipramins, SSRI, venlfaxin
Sodium oxybate: potent sedative: improves nocturnal sleep quality, EDS, and cataplexy.
