Human disease L17: Neurology 4 headache and CNS infections Flashcards
headaches are characterised, as either primary or secondary, which headace cause significant daily pain and disability, they are not dangerous from a physiological point of view.
primary headaches
headaches are characterised, as either primary or secondary, which headaches are caused by an underlying disease, like an infection, head injury, vascular disorders, brain bleed or tumors.
secondary headaches
which type of headache is associated with an underlying condition in the brain
secondary headaches
headaches that trigger red flags are based certain factors such as the sudden onset of a headache.
why does the development of a sudden onset compared to a gradual build up to a headache trigger a red flag?
a sudden onset could indicate that damage has been done to the head such as an injury or even a stroke.
which type of stroke is caused by bleeding into the space surrounding the brain.
Subarachnoid hemorrhage
SAH can be caused by a ruptured aneurysm, AVM, or head injury. One-third of patients will survive with good recovery; one-third will survive with a disability; and one-third will die.
which one of these is not a feature of raised intracranial pressure
whilst lying down
worse on positional change
strain
present on walking
nausea and vommiting
whilst lying down
if you exhibit focal neurology why is that considered a red flag
A focal neurologic deficit is a problem with nerve, spinal cord, or brain function.
It affects a specific location, such as the left side of the face, right arm, or even a small area such as the tongue.
Speech, vision, and hearing problems are also considered focal neurological deficits.
what is meningism
Meningism is the clinical syndrome of headache, neck stiffness, and photophobia, often with nausea and vomiting.
headaches are characterised, as either primary or secondary, which category does these type of headaches fall in to
tension headache
migraine
cluster headache
medication overuse headache
trigeminal neuralgia
primary headache
which of the primary headache disorders is referred to as having a tight band around your head
tension headaches
which primary headache occurs when the neck and scalp muscles become tense or contract.
The muscle contractions can be a response to stress, depression, head injury, or anxiety. They may occur at any age, but are most common in adults and older teens

what type of headache does the patient have and how would you treat it.
patient has tension headaches
treatment options would be conventional analgesia
prolonged reduction in cerebral blood flow, following a brief spell of increased flow, can result in what type of primary headache
migraine
which type of primary headaches have a bilateral manifestation
tension headaches
is where the arteries, particularly those at the side of the head (the temples), become inflamed. It’s serious and needs urgent treatment.
which condition is being described
Giant cell arteritis
also known as temporal arteritis
what causes high eye pressure
The cause of elevated eye pressure, known as ocular hypertension, is an imbalance in production and drainage of aqueous humor, the fluid inside your eye. Pressure builds as the eye creates new fluid and the channels which normally drain the aqueous humor become obstructed or damaged
what is aqueous humour
Aqueous humour is a thin, watery fluid produced by the eye, it is in the front of the eyeball between the lens and the cornea. and, in a healthy eye, it’s in a constant cycle of production and drainage.
is an infection of the protective membranes that surround the brain and spinal cord
which condition is being described
meningitis
meningitis is often caused by bacterial infection, what is the name of the bacteria that is responsible for infection in infants, adolescents, and young adults.
Neisseria meningitidis
meningitis is often caused by bacterial infection, what is the name of the bacteria that is responsible for infection in babies and elderly
streptococcus pneumoniae
