Dr took a Brain CT scan and said they saw a "focal infarction". What exactly is this?

---

I have been experiencing dizziness, shortness of breath, limbs that fall asleep often and just a feeling of being really unwell for about 4 weeks. My blood pressure has been flim flaming between low and high each time they take it and my pulse has been rather low at around 47-50 bpm. They did chest xray, blood work etc and all came back clear.Any ideas?
an infarction, not to scare you, is a spot of dead cells in the brain. I don't know what the focal part means...  (+ info)

Infarction in the brain?

---

Two and a half years ago I was informed that i have an infarction in the right side of my brain. I was on clopidogel then warfarin and back to clopidogel and now on aspirin. I am now constantly having that severe headache day and night. It has been more than two months now and the pain keeps increasing. At times i even feel dizzy. I have tried so many medication but they are not helping. Any advice as to how to deal with that headache or what medication i should take?
Headaches can't be cured, but they can be controlled. There are many medications that can either stop the pain associated with headaches or stop the symptoms, like nausea, that accompany them.

Using medication should be only one part of a wellness program. Life-style changes—such as avoidance of any known headache triggers, personal and family counseling, stress management, and relaxation therapy—should accompany any drug plan your doctor prescribes
Headaches that occur more than 15 days a month are considered chronic daily headaches. You may feel steady pain on one or both sides of your head. Sometimes the pain is described as a dull ache or a tight band of pressure around the head. The signs, symptoms and time frame vary depending on the specific type of chronic daily headache.

Chronic daily headaches affect up to 5 percent of adults. Treatment for any underlying diseases or conditions often stops chronic daily headaches. When no underlying diseases or conditions are present, treatment focuses on preventive medication.

Most headaches are nothing to worry about. But if headaches are disrupting your daily activities, work or personal life, it's time to take action. Headaches can't always be prevented, but your doctor can help you manage the signs and symptoms.

My sister is 24.MRI of her brain showed infarction in the left posterior parietal region...recovery?

---

Each part of the brain has its own function, therefore the neurological deficits that result from a stroke depend on the location in the brain it occurred. The left and right parietal lobes contain the primary sensory cortex, which controls sensation (touch and pressure), and a large association area that controls fine sensation (judgment of texture, weight, size, and shape). Damage to the left parietal lobe may disrupt a patient’s ability to understand spoken and/or written language. Her symptoms will depend on the exact location in the parietal lobe and the size of the region involved. If her stroke is truly in the posterior part of the parietal lobe, then her language center should not be affected and she should not have difficulties with speech or writing. If she does have difficulty with speech, she can work with a speech pathologist to improve this. She may have difficulty interpreting sensory information, but with therapy she should be able to learn to compensate for this. She is very young to have a stroke, therefore it is very important to determine the cause of her stroke so that her cause can be modified to reduce her chance of a future stroke. Out of all the areas of the brain to have a stroke the parietal lobe produces the least disabling symptoms. You should of course ask her doctor because he/she will know all the details of her stroke and prognosis for recovery. Good luck to you and your sister.  (+ info)

is there a specific treatment to infarction CVA ?

---

my father is 56 years old 3 years hypertensive newly diagnosed diabetes non smoker,thin , no heart problem had an infarction CVA 12 days back,MRI to his brain showed infarction in pons, had left hemiplegia after 4 days he started physiotherapy now he regained some power, I want to ask about prognosis and if he will be able to recover completely ? now his blood pressure is good after taking medication
Cerebrovascular Accident or CVA
Commonly called a stroke, cerebrovascular accident (CVA) is a sudden impairment of cerebral circulation in one or more of the blood vessels supplying the brain. CVA interrupts or diminishes oxygen supply and often causes serious damage or necrosis in brain tissues.

The sooner circulation returns to normal after CVA, the better chances are for complete recovery. However,about half of those who survive a CVA remain permanently disabled and experience a recurrence within weeks, months, or years.

What is the difference between infarction and gangrene?

---

The morphology of both is the same,that is,ischemic necrosis.I know gangrene involves putrefaction which infarction does not.Then,why is repair by fibrosis possible only in infarction,but not in gangrene?What are the exact definitions of infarction and gangrene?Please differentiate them clearly.
Infarction- (1) engorgement or stoppage of a vessel. (2) development or presence of an infarct (a localized area of ischemic necrosis produced by occlusion of the arterial supply or venous drainage of the part.)
Cardiac infarction- myocardial infarction.
cerebral infarction- an ischemic condition of the brain, causing a persistent focal neurological deficit in the area affected.
intestinal infarction- occlusion of an artery or arteriole in the wall of the intestine, resulting in the formation of an area of coagulation necrosis.
myocardial infarction- formation of an infarct in the heart muscle, due to interruption of the blood supply to the area.
pulmonary infarction- infiltration of an airless area of lung with blood cells, due to obstruction of the pulmonary artery by an embolus or thrombus.

gangrene- death of the tissue in considerable mass, usually associated with loss of vascular (nutritive) supply and followed by bacterial invasion and putrefaction.  (+ info)

20 yo son had abnor EKG-short PR interval. Echo showed no infarction. What would cause this? No info from MD.

---

He is on Thyroid hormone replacement, Metadate and is a pediatric brain tumor survivor. I wonder if radiation to the spine at age 7 could've caused some problem. I would like a little more info but the cardiologist just simply said no structural problems w/ the heart, take a copy of the EKG for future reference. Also, does this indicate any future problems we need to be aware of.
Sometimes the way we are positioned, or the way we move can throw the EKG machines off and the doctor can usually tell by looking at it, or comparing.

If he said dont worry, i wouldnt. My EKG once said I had long QT waves, and I was scared because of what it is, and read up on it, had a panic atttack went to the hospital and NOTHING. And QT waves dont go away.. the EKG machine was off..

Nothing is 100% accurate. But if you're unsure, take ihm to another doctor and see what they say.  (+ info)

How fast does nitroglycerin act when used to treat a myocardial infarction, i.e. when given in tablet form?

---

I have been trying to find information online about the speed and efficacy of nitroglycerin in tablet form when used to treat a myocardial infarction. It's for a short story I am writing, and I can't finish until I find this information. I don't want to just make something up.
Nitroglycerin doens't actually do anything to treat a myocardial infarction. It is best for angina- the squeezing pain people get in their chest when the blood vessels around their heart are constricted but not completely closed. For angina, it works in seconds to relieve the pain and relax those blood vessels so the heart gets more blood.
During a heart attack, the coronary vessels close completely, and blood flow to part of the heart is cut off. A person who takes nitroglycerin for angina should worry that they are having a heart attack if they take nitroglycerine and the pain does not go away. They should take an aspirin immediately and go to the ER to be given other meds or have a stent put in to open the artery back up.  (+ info)

Can pericardial effusion lead to myocardial infarction or any other serious consequence?

---

I am seeking to find out if pericardial effusion resulting from a viral infection can lead to myocardial infarction and/or any other serious consequence?
if left untreated it can lead to cardiac tamponade, which is compression of the heart due to a large increase of fluid in the pericardium. this condition is life-threatening as it prevents the heart from pumping effectively.  (+ info)

What is the main cuase of ischemia and how is it linked to myocardial infarction, along with thrombosis.?

---

Also with atheroma.

Im cofnused with the following terms and how they relate to cuasing myocardial infarction:
1)ischemia
2)thrombosis
3)atheroma
The buildup of atheroma or fatty plaque in the wall of the coronary artery narrows the lumen of the artery resulting in ischemia or inadequate blood flow to the heart. The atheroma may ulcerate releasing materials that cause blood to clot on the surface of the plaque. As the clot enlarges it totally obstructs the artery causing a myocardial infarction or death of cardiac tissue downstream to the obstruction.  (+ info)
