Cause of Migraine
|
> Neuronal discharges from upper brain stem and trigeminal system
> Lead to cerebral vasoconstriction (causing the headaches), > which results in cortical spreading depression > and changes in posterior cerebral cortical excitability (predisposing photopsias). |
|
Symptoms accompanying migraine
|
1. Nausea
2. Vomiting 3. Visual Auras |
|
Phases of Migraine
|
1. Prodrome phase
2. Aura phase 3. Headache (Pain) phase 4. Postdrome phase |
|
What happens during the aura and headache phase?
|
Cerebral blood flow and metabolism are reduced and followed by hyperemia (increased bloodflow)
These phases are associated with mental confusion and difficulty thinking due to a temporary imbalance of cerebral neurotransmitters and serotoninergic systems. |
|
Which medicines help during a migraine attack? And what do they do?
|
Injecting sumatriptan stimulates 5HT (serotonin) receptors) and receptors of blood vessels, which corrects the neuronal and cerebro-vascular transmitter disorder, with restoration of the neuronal 5HT function back to normal.
|
|
Does depression influences psychometric testscores with vascular headaches?
|
No.
|
|
There are 4 different types of headache sufferers:
|
1. Migraine with aura
2. Migraine without aura 3. Migraine converted to chronic daily headaches 4. Cluster headaches |
|
The "mini" test battery for patients with vascular headaches consists of?
|
1. Mini Mental State Examination (MMSE)
2. Cognitive Capacity Status Examination (CCSE) 3. Hamilton Depression Rating Scales (HDRS) All tests can be used headache present/absent |
|
Headache-related cognitive declines involves (7):
|
1. Attention
2. Immediate Recall 3. Digit Retention 4. Arithmetic 5. Calculation 6. Acquisition of new words 7. Abstract Thinking > Overall cognitive functioning |
|
Which variables were of influence on cognitive decline during vascular headaches?
|
1. Age: CCSE scores declined more for younger subjects.
2. Gender: CCSE scores declined more for women. |
