Sleep disturbances
Another common and under-recognized cause of hypertension is sleep apnea, which is often best treated with nocturnal nasal continuous positive airway pressure (CPAP), but other approaches include the Mandibular advancement splint (MAS), UPPP, tonsillectomy, adenoidectomy, septoplasty, or weight loss. Another cause is an exceptionally rare neurological disease called Binswangers disease, causing dementia; it is a rare form of multi-infarct dementia, and is one of the neurological syndromes associated with hypertension. Arsenic exposure
Because of the ubiquity of arsenic in ground water supplies and its effect on cardiovascular health, low dose arsenic poisoning should be inferred as a part of the pathogenesis of idiopathic hypertension. Idiopathic and essential are both somewhat synonymous with primary hypertension. Arsenic exposure has also many of the same signs of primary hypertension such as headache, somnolence,
confusion, proteinuria
visual disturbances, and nausea and vomiting

Potassium deficiency
Due to the role of intracellular potassium in regulation of cellular pressures related to sodium, establishing potassium balance has been shown to reverse hypertension. Diagnosis
The ABCDE mnemonic can be used to help determine a secondary cause of hypertension

A: Accuracy, Apnea, Aldosteronism
B: Bruits, Bad Kidney
C: Catecholamines, Coarctation of the Aorta, Cushings Syndrome
D: Drugs, Diet
E: Erythropoietin, Endocrine Disorders

Ménières disease (MD) is a disease of the inner ear that is characterized by potentially severe and incapacitating episodes of vertigo, tinnitus, hearing loss, and a fullness in the ear. Typically, only one ear is affected initially, but over time, both ears may become involved. Episodes generally last from 20 minutes to a few hours. The time between episodes varies. The hearing loss and ringing in the ears can become constant over time.The cause of Ménières disease is unclear, but likely involves both genetic and environmental factors. A number of theories exist for why it occurs, including constrictions in blood vessels, viral infections, and autoimmune reactions. About 10% of cases run in families. Symptoms are believed to occur as the result of increased fluid buildup in the labyrinth of the inner ear. Diagnosis is based on the symptoms and a hearing test. Other conditions that may produce similar symptoms include vestibular migraine and transient ischemic attack.No cure is known. Attacks are often treated with medications to help with the nausea and anxiety. Measures to prevent attacks are overall poorly supported by the evidence. A low-salt diet, diuretics, and corticosteroids may be tried. Physical therapy may help with balance and counselling may help with anxiety. Injections into the ear or surgery may also be tried if other measures are not effective, but are associated with risks. The use of tympanostomy tubes, while popular, is not supported.Ménières disease was first identified in the early 1800s by Prosper Ménière. It affects between 0.3 and 1.9 per 1,000 people.
