They can include

Dry or sore throat
Coughing (both a causal factor and a symptom of laryngitis)
Frequent throat clearing
Increased saliva production
Dysphagia (difficulty swallowing)
Sensation of swelling in the area of the larynx (discomfort in the front of the neck)
Globus pharyngeus (feeling like there is a lump in the throat)
Cold or flu-like symptoms (which, like a cough, may also be a causal factor for laryngitis)
Swollen lymph nodes in the throat, chest, or face
Fever
General muscle pain (myalgia)
Shortness of breath, predominantly in children

Voice quality
Aside from a hoarse-sounding voice, changes to pitch and volume may occur with laryngitis. Speakers may experience a lower or higher pitch than normal, depending on whether their vocal folds are swollen or stiff. They may also have breathier voices, as more air flows through the space between the vocal folds (the glottis), quieter volume and a reduced range. Causes
Laryngitis can be infectious as well as noninfectious in origin. The resulting inflammation of the vocal folds results in a distortion of the sound produced there. It normally develops in response to either an infection, trauma to the vocal folds, or allergies. Chronic laryngitis may also be caused by more severe problems, such as nerve damage, sores, polyps, or hard and thick lumps (nodules) on the vocal cords. [4]

Acute
Viral
Most acute cases of laryngitis are caused by viral infections, the most common of which tend to be rhinovirus, influenza virus, parainfluenza virus, adenovirus, coronavirus, and RSV. In patients who have a compromised immune system, other viruses such as herpes, HIV may also be potential causes.
Cognitive deficits in patients with schizotypal personality disorder are very similar to, but quantitatively milder than, those for patients with schizophrenia. A 2004 study, however, reported neurological evidence that did "not entirely support the model that SPD is simply an attenuated form of schizophrenia". Epidemiology
Reported prevalence of STPD in community studies ranges from 0.6% in a Norwegian sample, to 4.6% in an American sample. A large American study found a lifetime prevalence of 3.9%, with somewhat higher rates among men (4.2%) than women (3.7%). It may be uncommon in clinical populations, with reported rates of up to 1.9%.Together with other cluster A personality disorders, it is also very common among homeless people who show up at drop-in centres, according to a 2008 New York study. The study did not address homeless people who do not show up at drop-in centres.Cannabis users, whether that be a lifetime use, abuse or dependence, have been found to have an increased likelihood of possessing schizotypal personality disorder or traits consistent with STPD. Another epidemiological study on suicidal behavior in STPD found that, even when accounted for sociodemographic factors, people with STPD were 1.51 times more likely to attempt suicide. The same study found that people with childhood adversities, specifically abuse by a parent or caretaker, have a strongly significant association with lifetime STPD. See also
