What is a common symptom of Familial Dysautonomia?

Familial Dysautonomia, also known as Riley-Day syndrome, is a genetic condition that affects the autonomic nervous system, leading to various symptoms primarily due to the dysfunction of sensory and autonomic nerves. A common manifestation of this disorder is a decreased ability to taste, as individuals may have altered or diminished taste sensations. This occurs because the disease impacts the sensory nerves that relay taste information.

Loss of smell and excessive sweating can be associated with other conditions affecting the autonomic nervous system but are not as directly linked to the hallmark features of Familial Dysautonomia. Severe headaches, while they can occur in many medical conditions, are not a typical symptom of this syndrome.
