She was able to remember how to read music and the techniques used in art. She had preserved skill-related declarative memory for some things even though she had deficits in other declarative memory tasks. She even scored higher on skill-related declarative memory than the control in watercolor techniques, a technique that she used in her professional career before she acquired amnesia. Semantic Information
The loss of semantic information in amnesia is most closely related with damage to the medial temporal lobe or to the neocortex.Some patients with anterograde amnesia can still acquire some semantic information, even though it might be more difficult and might remain rather unrelated to more general knowledge. H.M. could accurately draw a floor plan of the home in which he lived after surgery, even though he had not lived there in years. There is evidence that the hippocampus and the medial temporal lobe may help to consolidate semantic memories, but then they are more correlated with the neocortex. While lesions of the hippocampus normally lead to the loss of episodic memory, if there is any effect on semantic memory, it is more varied and usually does not last as long. Episodic Information
One reason that patients could not form new episodic memories is likely because the CA1 region of the hippocampus has a lesion, and thus the hippocampus could not make connections to the cortex. After an ischemic episode (an interruption of the blood flow to the brain), an MRI of patient R.B.
In the absence of heart failure, hypertension, with or without enlargement of the heart (left ventricular hypertrophy) is usually symptomless.Symptoms, signs and consequences of congestive heart failure can include:

Fatigue
Irregular pulse or palpitations
Swelling of feet and ankles
Weight gain
Nausea
Shortness of breath
Difficulty sleeping flat in bed (orthopnea)
Bloating and abdominal pain
Greater need to urinate at night
An enlarged heart (cardiomegaly)
Left ventricular hypertrophy and left ventricular remodeling
Diminished coronary flow reserve and silent myocardial ischemia
Coronary heart disease and accelerated atherosclerosis
Heart failure with normal left ventricular ejection fraction (HFNEF), often termed diastolic heart failure
Atrial fibrillation, other cardiac arrhythmias, or sudden cardiac deathHeart failure can develop insidiously over time or patients can present acutely with acute heart failure or acute decompensated heart failure and pulmonary edema due to sudden failure of pump function of the heart. Sudden failure can be precipitated by a variety of causes, including myocardial ischemia, marked increases in blood pressure, or cardiac arrhythmias. Diagnosis
Differential diagnosis
Other conditions can share features with hypertensive heart disease and need to be considered in the differential diagnosis. For example:
Coronary artery disease or ischemic heart diseases due to atherosclerosis
Hypertrophic cardiomyopathy
Left ventricular hypertrophy in athletes
Congestive heart failure or heart failure with normal ejection fraction due to other causes
Atrial fibrillation or other disorders of cardiac rhythm due to other causes
Sleep apnea

Prevention
Because there are no symptoms with high blood pressure, people can have the condition without knowing it.
