A stroke is a medical condition in which poor blood flow to the brain causes cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly.Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours, the stroke is a transient ischemic attack (TIA), also called a  mini-stroke. A hemorrhagic stroke may also be associated with a severe headache. The symptoms of a stroke can be permanent. Long-term complications may include pneumonia and loss of bladder control.The main risk factor for stroke is high blood pressure. Other risk factors include  high blood cholesterol, tobacco smoking, obesity, diabetes mellitus, a previous TIA, end-stage kidney disease, and atrial fibrillation. An ischemic stroke is typically caused by blockage of a blood vessel, though there are also less common causes. A hemorrhagic stroke is caused by either  bleeding directly into the brain or into the space between the brains membranes. Bleeding may occur due to a ruptured brain aneurysm. Diagnosis is typically based on a physical exam and supported by medical imaging such as a CT scan or MRI scan.
It is difficult to quantify by subjective complaints or clinical examinations alone, hence both clinicians and researchers depend both on concurrent subjective assessment and on objective measurement of the nasal airway.Prevalence of  kyphosis has been linked to nasal obstruction in a study. Treatment
According to WebMD, congestion can be addressed through the use of a humidifier, warm showers, drinking fluids, using a neti pot, using a nasal saline spray, and sleeping with ones head elevated. It also recommends a number of over the counter decongestants and antihistamines. A 2012 study concluded that combining nasal sprays with "nasal breathing exercises" (NBE) led to improvement of symptoms. Though it may seem weird, crying can also be helpful.The Cleveland Clinic also states that congestion may be a sign of a deviated septum, a condition that needs to be addressed by a doctor. See also
