Understanding Abductor Spasmodic Dysphonia
Abductor spasmodic dysphonia is a condition characterized by spasms that cause the vocal cords to inappropriately open, resulting in the escape of air while speaking. This abnormality prevents normal vibration of the vocal cords, leading to a voice that may sound weak and breathy. Unlike other vocal disorders, such as adductor spasmodic dysphonia, the spasms in abductor spasmodic dysphonia typically do not occur during laughter, crying, or shouting. However, in rare cases, individuals may experience a combination of both adductor and abductor spasmodic dysphonia, which is referred to as mixed spasmodic dysphonia.
Risk Factors
While the exact causes of this condition are not yet fully understood, there are several known risk factors that can increase the likelihood of developing it. One such factor is infections of the upper respiratory tract, which can elevate a person’s overall risk. Additionally, injuries to the larynx can also make the condition more probable.
Another risk factor for spasmodic dysphonia is persistent overuse of the voice. Individuals who consistently strain their vocal cords are at a higher risk of developing this condition. Furthermore, periods of psychological stress can also contribute to the onset of spasmodic dysphonia.
