Cerebral Atrophy
Blood vessels carry oxygen and nutrients to the brain. When these blood vessels are blocked by a clot strokes occur.
Symptoms of cerebral atrophy include dementia, seizures, loss of motor control, and difficulty with speaking, comprehension or reading
Diagnosing cerebral atrophy can be achieved by use of a CT scan , MRI scan , PET scan , or a Single-photon emission computed tomography (SPECT).
Because there is no cure for cerebral atrophy, treating the symptoms become more of the focus. Treatment includes medications, physical therapy and psychological counseling and support.
If no treatment occurs then a person may not be able to participate in normal activities, lose their independence or become depressed.
Cardiac Hypertrophy
When there is increased stress on the heart, hypertrophy of the heart muscle occurs. There are two ventricles of the heart; the right ventricle ...view middle of the document...
Echocardiogram and EKGs are also used in diagnosing cardiac hypertrophy.
Depending on the underlying cause of the condition will determine whether surgery or medication is needed. Medications include: Angiotensin-converting enzyme (ACE) inhibitors, Angiotensin II receptor blockers (ARBs), Thiazide diuretics Beta blockers and/or Calcium channel blockers
If cardiac hypertrophy is not treated heart failure, arrhythmia, ischemic heart disease, heart attack or cardiac arrest may occur.
Summary Post
As a result of this week’s discussion, I’ve learned more about the changes in cells and tissues after an injury has occurred. There were a few conditions that could be treated with medication or surgery, while others have no cure at all. I got a better understanding of cerebral atrophy and cardiac hypertrophy. At first, I couldn’t quite grasp the pathophysiology of dysplasia as the result of an abnormal pap smear but after reading a few DQ post, I’m a bit more informed than when I first read about it in my textbook. The preventive measures for cervical dysplasia are practiced through making positive lifestyle choices. Overall, pathophysiology seems as if it’s going to be an interesting topic to learn.

Summary Post
This week, we touched on the metric system. We learned the basic units of measure and the different methods for conversion. I’ve relearned facts about the metric system and dosage calculations in adults and children. I’m glad there was a math review portion in our reading. It’s amazing what we forget, when it’s not practiced on a regular basis. I picked back up on it pretty quickly though. I’ve also learned why the metric system is only used in US hospitals.
When blood flows too slowly, cells in the blood begin to stick together and form clumps. High counts of red blood cells and particles, low temperatures, and high concentrations of fat can lead to an increase in blood thickness. When blood flows too fast, this means there is more fluid in the blood. This causes low blood pressure.
