Are there different types of dysautonomia?

Dysautonomia is a medical term for a group of different conditions that share a common problem – improper functioning of the autonomic nervous system. Some of the conditions caused by primary dysautonomia include:

• Neurocardiogenic syncope (NCS): NCS is the most common form of dysautonomia. It can cause fainting spells that happen once or twice in your lifetime or multiple times every day. NCS is also called situational syncope or vasovagal syncope.
• Postural orthostatic tachycardia syndrome (POTS): A disorder that causes problems with circulation (blood flow), POTS can cause your heart to beat too fast when you stand up. It can lead to fainting, chest pain and shortness of breath.
• Familial dysautonomia (FD): People inherit this type of dysautonomia from their genetic relatives. It can cause decreased pain sensitivity, lack of eye tears and trouble regulating body temperature. FD is more likely to affect Jewish people (Ashkenazi Jewish heritage) of Eastern European heritage.
• Multiple system atrophy (MSA): A life-threatening form of dysautonomia, multiple system atrophy develops in people over 40 years old. It can lead to heart rate issues, low blood pressure, erectile dysfunction and loss of bladder control.
• Pure autonomic failure: People with this form of dysautonomia experience a fall in blood pressure upon standing and have symptoms including dizziness, fainting, visual problems, chest pain and tiredness. Symptoms are sometimes relieved by lying down or sitting.
