Hyperventilation syndrome (HVS), also known as chronic hyperventilation syndrome (CHVS), dysfunctional breathing hyperventilation syndrome, cryptotetany, [1] [2] spasmophilia, [3] [4] [5] latent tetany, [4] [5] and central neuronal hyper excitability syndrome (NHS), [3] is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply or too rapidly ...
Deliberately inhaling solvents from an attached paper or plastic bag or in a closed area greatly increases the chances of suffocation. Brain damage is typically seen with chronic long-term use as opposed to short-term exposure. [6] Parkinsonism (see: Signs and symptoms of Parkinson's disease) has been associated with huffing. [36]
Salbutamol is typically used to treat bronchospasm (due to any cause—allergic asthma or exercise-induced), as well as chronic obstructive pulmonary disease. [8] It is also one of the most common medicines used in rescue inhalers (short-term bronchodilators to alleviate asthma attacks). [17] As a β 2 agonist, salbutamol also has use in ...
Published studies emphasize anxiety or stress as a primary cause while more recent literature indicates a likely physical etiology. [citation needed] This disorder has been observed from infancy through old age, with the observation of its occurrence in infants leading some to believe that a physiological cause such as reflux or allergy is ...
A link between these types of drugs and cognitive impairment isn't a totally new discovery, but for the first time, researchers used brain imaging techniques to determine the physical changes ...
Bipolar disorder can cause manic episodes ranging fro different sudden mood changes. AUD can also be used to stall the same symptoms expressed in depression as well as with bipolar disorder. In some cases AUD can cause other brain disorders to worsen itself, or the symptoms of the disorder.
Substance avoidance can be important in reducing anxiety and panic symptoms, as many substances can cause, exacerbate, or mimic symptoms of panic disorder. For example, caffeine has been known to have anxiety and panic-inducing properties that can especially present in those who are more susceptible to panic attacks. [ 60 ]
The respiratory center of the brain is located in the pons and medulla and is primarily driven by elevated carbon dioxide levels in the blood (hypercapnia) with decreased oxygen levels serving as a less potent stimulus. [9] Central nervous system disorders, such as stroke and tumors, may cause hypoventilation. Drugs may decrease respiratory ...
