neurologic disorders Prof. Sittie Adaweyah L. Macabago, DM-HCAc, MAN, LPT, RN  A cerebrovascular disorder is an umbrella term that refers to a functional abnormality of the central nervous system (CNS) that occurs when the normal blood supply to the brain is disrupted.  Two major categories: (1)Ischemic stroke (2)Hemorrhagic stroke  An ischemic stroke, cerebrovascular accident (CVA), or “brain attack” is a sudden loss of function resulting from disruption of the blood supply to a part of the brain.  5 different types based on the cause: (1)large artery thrombotic strokes (2)small penetrating artery thrombotic strokes (3)cardiogenic embolic strokes (4)cryptogenic strokes (5)Other rain Aneurysm ) 8,5440, Risk factors  Hypertension I Atrial fibrillation  Hyperlipidemia  Diabetes Mellitus = Smoking  Asymptomatic carotid stenosis  Obesity = Excessive alcohol consumption Clinical Manifestations:  Numbness or weakness of the face, arm, or leg, especially on one side of the body  Confusion or change in mental status  Trouble speaking or understanding speech  Visual disturbances  Difficulty walking, dizziness, or loss of balance or coordination  Sudden severe headache  Primary prevention of ischemic stroke remains the best approach. Stroke risk screenings are an ideal opportunity to lower stroke risk by identifying people or groups of people who are at risk for stroke and by educating patients and the community about recognition and prevention of stroke.  STREPTOKINASE - used to treat ischemic stroke by dissolving the blood clot that is blocking blood flow to the brain. NURSING MANAGEMENT  SOP nursing care  Medications  Laboratories (blood chemistry)  Provide information on the disease and preventions  are caused by bleeding into the brain tissue, the ventricles, or the subarachnoid space. Primary intracerebral hemorrhage from a spontaneous rupture of small vessels accounts for approximately 80% of hemorrhagic strokes and is caused chiefly by uncontrolled hypertension. Types: (1)Intracerebral hemorrhage (2)Intracranial (cerebral) aneurysm (3)Arterio-venous Malformations (AVM) (4)Subarachnoid Hemorrhage  Exploding headache  Decreased level of consciousness  Sluggish pupillary reaction  Motor and sensory dysfunction  Cranial nerve deficits  Speech difficulties and visual disturbances  Vasospasm  Seizures  Hydrocephalus enlargement  Re-bleeding  Hypo-natremia - t sodium \  Modifying lifestyle  Control of hypertension  Diet modification  Exercise  The patient is closely monitored for neurologic deterioration resulting from recurrent bleeding, increasing ICP, or vasospasm.  A neurologic flow record is maintained.  The blood pressure, pulse, level of consciousness, pupillary responses, and motor function are checked hourly.  Respiratory status is monitored, because a reduction in oxygen I areas of the brain with impaired auto- regulation increases the chances of a cerebral infarction.  Primarily supportive and consists of bed rest with sedation to prevent agitation and stress, management of vasospasm, and surgical or medical treatment to prevent re- bleeding. Analgesics may be prescribed for head and neck pain.  The patient is fitted with sequential compression devices to prevent deep vein thrombosis (DVT). An abnormal tangle of blood vessels connecting arteries and veins.

In this disease there is an inflammation on the seventh cranial nerve, which largely occurs due to wind, infection or damage in the ears. virus (Epstein Barr, herpes or cytomegaly) >>> nerve infection >>> facial paralysis >>> prolonged untreated causes permanent facial distortion - eyes do not shut completely - mouth gets twisted and saliva dribbles from one side. - The affected cheek cannot be blown completely - Sometimes there can be pain behind the ear - extra sounds in the ears - loss of taste in the tongue. - Steroids - optimum physiotherapy - proper eye care - use of antiviral agents (like acyclovir in herpes virus infection) - supportive measures In this disease, there is progressive cell degeneration in the region of the brain known as substantia nigra reducing the formation of an extremely important biochemical substance, dopamine. It spreads to other side after few years. >>> aging-/unknown >>> degeneration substantia nigra >>> decrease production of dopamine/inability to absorb dopamine properly >>> motor involuntary mov’ts ─ lethargy - decrease in co-ordination - Tremors - rigidity of muscles - fingers of the hands and legs shake in a peculiar manner (pill-rolling movement or rhythmic movement as if the patient is counting money.) - stoops and his gait shuffles and there is poor arm swinging - Slow movement - Muscles slowly become rigid - Handwriting becomes smaller - Speed of walking becomes slow - decrease in memory - depression with increased perspiration and body ache - no treatment or medicine available to -stop the destruction of the cells. - Exercise TO LESSEN THE PROGRESSION - Counseling - Medical treatment consists of levodopa (able to cross BBB) - Nutritional evaluation  TB Meningitis  viral/fungal  There is a possibility that the tuberculosis in the chest may be there for a long time, but a decrease in the immunity of the body due to any cause may result in TB of the brain.
