This condition causes blood blisters to form on the inner cheek, gums, tongue and/or the roof of the mouth. It is caused by the herpes simplex virus 1 and symptoms, like pain, a burning sensation, fatigue and fever, will be felt. You will consistently find a blood blister in the mouth of alcoholics, because alcohol can cause ulcerations inside your mouth.
Sudden hearing loss after stroke is less common than other neurological impairments, but it may be the initial presentation of vertebrobasilar ischemia, which is more common in the presence of vascular risk factors (Kim & Lee, 2009; H. Lee & Baloh, 2005; H. Lee & Cho, 2003; H. Lee et al., 2002; H. Lee, Whitman, Lim, Lee, & Park, 2001).
March 10, 2003. Introduction: Sensorineural hearing impairment alters sound perception in a complex nonlinear manner. The relative amplitudes of harmonics and temporal modulations are among the many characteristics of sound that are altered, resulting in distorted percepts such as timbre and loudness. These changes to the perception of sound due to hearing impairment affect both speech intelligibility and sound quality.
