Plexus disorders can be particularly disabling because lesions in the plexus usually affect large groups of nerve fibers originating from several spinal levels. Electrodiagnostic studies are often required to confirm a plexus lesion and determine the extent of injury and prognosis. Magnetic resonance is the imaging modality of choice for detecting intrinsic nerve abnormalities; recently, high-resolution ultrasound has emerged as an alternative method for dynamic evaluation and visualization of internal nerve architecture. Once a plexopathy is confirmed, the list of possible etiologies is relatively limited and includes traumatic and nontraumatic causes.

Novel treatments now include antisense oligonucleotide and RNA interference drugs, whereas new applications such as CRISPR and amyloid antibodies are being studied for potential use in the future. These treatments have dramatically improved quality of life and increased survival in patients with ATTRv. Despite these breakthroughs, many challenges remain. Some of these challenges include early recognition and diagnosis of ATTRv, monitoring and initiation of treatment in asymptomatic or paucisymptomatic carriers, adequate treatment in people with mixed phenotype (i.e., cardiac and neurological), and the emergence of new phenotypes in people living longer with the disease (i.e., central nervous system and ocular complications).

Pediatric neuropalliative medicine is a recently developed area of subspecialty practice that supports families affected by serious neurological illness in navigating uncertain illness trajectories, refractory symptoms, and the myriad medical decisions that arise over the life of the child. Despite their medical needs, children with neurological diseases live full, joyful, and connected lives with their families, many of whom also experience personal growth and find meaning in their caregiving. Patients and families under the care of neurologists also face many systemic and interpersonal biases, both within the health care system and in the community, and encounter frequent gaps in their home and community-based supports. This chapter summarizes what is known about pediatric neuropalliative medicine and highlights the future research, educational, and clinical innovations that are needed to build more comprehensive and well-prepared systems to address unmet needs. Particularly in the modern era of child neurology practice where disease-modifying treatments are becoming increasingly available, pediatric neuropalliative medicine is an essential area of subspecialty practice that helps to support the personhood and quality of life of the individuals affected by serious illness and their families.
