diabetes insipidus
deficiency of adh or decreased response to adh, unable to concentrate urine, increased voiding and dehydration
siadh
failure of negative feedback, adh secretion continues despite serum osmolality, decreased urine output, water retention
type 1 diabetes
destruction of pancreatic beta cells to lose beta cell function with absolute insulin deficiency
type 2 diabetes
insulin resistance with either relative insulin deficiency or impaired release of insulin for blood glucose levels due to beta cell dysfunction
manifestations of diabetes
polyuria, polydipsia, polyphagia (occurs more with type 1)
hypoglycemia
below normal blood glucose levels due to relative insulin excess, can cause altered cerebral function and activation of ans,
diabetic ketoacidosis
type 1, hyperglycemia, ketosis, metabolic acidosis, compensation with kussmal respirations, hyperkalemia
hhnks
type 2, hyperglycemia, hyperosmolarity/dehydration, absence of ketoacidosis,
diabetic nephropathy
proteinuria, lesions of glomeruli, microvascular complication, leading cause of renal failure
diabetic retinopathy
microvascular complication, leading cause of acquired blindness, increased risk for cataracts and glaucoma
diabetic neuropathy
peripheral nerve dysfunction with decreased sensation and autonomic dysfunction
macrovascular complications
cardiovascular disease, cerebrovascular disease, PAD
alzheimers
most common dementia with slow onset, neuritic plaques and tangles, diagnosis via exclusion
initial stage Alzheimers
short term memory loss, mild personality changes
moderate stage Alzheimers
more global cognitive impairment, language impaired, personal hygiene issues, behavioral changes, need supervised placement
last stage Alzheimers
lose ability to respond to environment and require total care
parkinsons
degeneration of basal ganglia causing loss of dopamine producing neurons
cardinal signs of parkinsons
tremor, rigidity, bradykinesia, postural instability
myasthenia gravis
disorder of neuromuscular junctions that affect impulse transmission between motor neuron and innervated muscle cell, autoimmune disorder, causes diplopia, muscle weakness, ptosis of eyelid
myasthenia crisis
muscle weakness compromises breathing
multiple sclerosis
demyelination of nerve fibers in white matter of cns, slows conduction
chief complaints of ms
paresthesias, optic neuritis, diplopia, gaze paralysis
relapsing remitting phase of ms
episodes of acute worsening, recovery and stable disease between relapses
primary progressive phase of ms
nearly continuous neurological deterioration from onset of symptoms
secondary progressive phase of ms
gradual neurological deteriation with or without superimposed acute relapses
progressive relapsing phase of ms
gradual neurological deterioration from onset, has subsequent superimposed relapses
spinal shock phase
