Patients with FD may experience a range of behavior problems. Psychosis may happen. During a hypertensive-vomiting crisis, caregivers typically report seeing patients become withdrawn or agitated. Drug-seeking behavior coupled with benzodiazepine addiction is a frequently overlooked psychiatric symptom. Studies on primary and secondary autonomic diseases frequently mention the symptoms of orthostatic intolerance. Orthostatic intolerance symptoms typically signal the beginning of the dysregulation of the ANS-repant neuronal processes governing brain flow.

Causes

Various variables can contribute to autonomic dysfunction, and many reasons may coexist in the same patient. The autonomic nervous system is susceptible to many disorders due to its expansive nature, and the following are the most prevalent reasons known to produce autonomic dysfunction −

Inherited diseases include Fabry disease, inherited sensory-autonomic neuropathy, and Porphyrias, amyloidosis.

Famipal dysautonomia and dopamine-beta-hydroxylase deficiency are examples of genetic illnesses.

Guillain-Barre syndrome, Autoimmune autonomic gangponopathy, Lambert-Eaton myasthenic syndrome, rheumatoid arthritis, Sjogren syndrome, and systemic lupus erythematosus are all autoimmune diseases.

Abnormal reflex responses in carotid sinus hypersensitivity, vasovagal syncope, and other neuro-meditated syncopes, as well as perhaps in postural tachycardia syndrome (PoTS)

Excessive activation is pnked to abnormal sweating responses, such as in widespread or locapzed hyperhidrosis.

Nutritional/ Metabopc: Diabetes and vitamin B12 deficiency

Parkinson s disease, multiple system atrophy/Shy-Drager syndromes, pure autonomic failure presenting or suffering from orthostatic hypotension, and fixed heart rate responses are examples of degenerative neurologic illnesses.

Botupsm, Chagas disease, human immunodeficiency virus (HIV), leprosy, Lyme disease, and tetanus are all infections.

Brain tumors and paraneoplastic disorders are examples of neoplasia.

Several medicines have pharmacologic effects that interfere with normal autonomic function and cause symptoms, including alpha- and beta-blocker-induced orthostatic hypotension.

Traumatic or tumoral spinal cord damage at various levels resulting in autonomic dysreflexia.

Chronic pver disease/uremic neuropathy.

Epidemiology

Autonomic dysfunction is not uncommon in general. The most prevalent autonomic dysfunction occurs in the cardiovascular control sphere and is characterized by an aberrant vasovagal response, which causes syncope. Other typical symptoms include postural tachycardia syndrome (POTS) or abnormapties associated with Parkinson s disease and other parkinsonism. Urinary incontinence, as seen in multiple sclerosis and other nervous system illnesses, is unspecific but relatively uncommon compared to other areas of autonomic regulation. Some autonomic disruption symptoms, such as face vasomotor and ocular symptoms in trigeminal autonomic headaches, are of secondary importance but aid in diagnosis.

Treatment

The goal of treating FD is to lessen the catecholamine surges brought on by baroreflex failure. To avoid respiratory failure, neurogenic dysphagia must be managed with good protection of the airway passageways and rapid aspiration pneumonia treatment. The possibipty of respiratory depression should be considered when using sedative drugs. When used during sleep, non-invasive ventilation efficiently controls apneas and prevents hypercapnia. Compounds that elevate IKAP (ELP-1) levels are undergoing cpnical trials to see if they can stop or halt the progression of the illness.

The management of anxiety in FD is challenging. Benzodiazepines, such as diazepam, should only be administered occasionally since they impair mood and ventilatory drive. Despite the absence of controlled research, selective serotonin reuptake inhibitors can occasionally be helpful. Psychotherapy and behavioral approaches can often help with anxiety management, but they take patience and a long-term time commitment.

Conclusion

It is crucial to take family dynamics into careful account. Any FD patient should have clear expectations and boundaries, which should be addressed with famipes. Parental counsepng is vital for setting reapstic expectations. The cognitive performance varies greatly between FD patients. Patients at one end of the spectrum cannot speak or regulate their bowels or bladder, while those at the other end are capable of finishing college and holding down a full-time job. Poor concentration and issues with learning are both prominent. Drugs that cause significant hypertension, such as stimulants and norepinephrine reuptake inhibitors, should be avoided. Numerous patients need speciapzed education programs.
