The main difference between SUNCT and SUNA is the clinical presentation of the secondary autonomic symptoms. In SUNCT, both conjunctival injection (red eyes) and lacrimation on the same side of the headache should be present. In SUNA, one or both of these two symptoms are absent, and other autonomic symptoms may be present instead. SUNA attacks ...
Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) Short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA) Long-lasting autonomic symptoms with hemicrania (LASH) TACs can be differentiated by the length and frequency of recurrence of the headaches. [3]
Retrospective surveys indicated that paroxysmal hemicrania was more common in women. [1] [2] However, subsequent prospective research showed an equal prevalence between females and males, with a ratio close to 1:1. [3] Unlike in migraine, it has no neurological symptoms associated with it.
[1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals. Because most people are not diagnostically trained or knowledgeable, they typically describe their symptoms in layman's terms, rather than using specific medical terminology. This list is not exhaustive.
However, women may have longer and more severe cluster headaches. [11] The onset of an attack is rapid and typically without an aura. Preliminary sensations of pain in the general area of attack, referred to as "shadows", may signal an imminent cluster headache, or these symptoms may linger after an attack has passed, or between attacks. [12]
Here, on the differential diagnosis between SUNCT and CH it says "However, cluster headaches usually last longer (up to three hours), occur less often (three to five attacks per day), and do not accompany cranial autonomic symptoms."
Signs and symptoms are also applied to physiological states outside the context of disease, as for example when referring to the signs and symptoms of pregnancy, or the symptoms of dehydration. Sometimes a disease may be present without showing any signs or symptoms when it is known as being asymptomatic . [ 13 ]
Ischemic optic neuropathy (ION) is the loss of structure and function of a portion of the optic nerve due to obstruction of blood flow to the nerve (i.e. ischemia).Ischemic forms of optic neuropathy are typically classified as either anterior ischemic optic neuropathy or posterior ischemic optic neuropathy according to the part of the optic nerve that is affected.
