Cerebral amyloid angiopathy is a common pathology in the aging brain, most often recognized in clinical practice as the cause of multiple, strictly lobar intracerebral hemorrhages, microbleeds, or superficial sulcal/meningeal bleeding. Advanced cerebral amyloid angiopathy is also associated with nonhemorrhagic brain lesions. A subset of cerebral amyloid angiopathy presents with subacute mental status changes, headache, seizures, and amyloid-related vascular inflammation.

Postural orthostatic tachycardia syndrome (POTS) is an often-disabling syndrome of symptomatic orthostatic tachycardia in the absence of orthostatic hypotension. POTS has been associated with a wide variety of conditions, including diabetes, some autoimmune disorders, infections, trauma, surgery, stress, mastocytosis, and the hypermobility type of Ehlers-Danlos syndrome. Palpitations, dizziness, and other symptoms of POTS occur mainly when standing upright and are typically relieved by sitting or lying flat.

Although patients have multisystem involvement of amyloidosis, cardiomyopathy and peripheral neuropathy with autonomic neuropathy are typically the most prominent disease manifestations and the primary drivers of disability and mortality.
