What are the symptoms of He's syndrome?

Homer's syndrome refers to Alzheimer's disease. Typical symptoms of Alzheimer's disease include miosis (pupil constriction), reduced facial sweating, and enophthalmos (posterior displacement of the eyeball). A detailed analysis is as follows:

1. Miosis

Homer's syndrome is a neurological disorder, typically caused by damage to the sympathetic nerves, leading to a series of symptoms on one side of the face. The specific manifestations may vary depending on the underlying cause, severity, and location of the lesion. Damage to the sympathetic nerves can result in pupil constriction, causing asymmetry in the appearance of the eyes in some patients.

2. Reduced Facial Sweating

Patients may experience loss of function in sweat glands on one side of the face, resulting in dry skin and decreased sweating.

3. Enophthalmos

Due to damage to the sympathetic nerves, the muscles within the orbit where the eyeball resides lose their tone, causing the eyeball to sink backward, giving the appearance of sunken eyes.

In addition to the above symptoms, ptosis (drooping of the upper eyelid) may also occur. This condition may be caused by central nervous system disorders, neck trauma, carotid artery dissection, or other reasons. Detailed neurological examinations, imaging studies, and other relevant tests are required to determine the exact cause.
