The clinical studies performed so far have shown that cellular grafts can survive, grow, and function also in the diseased adult human brain. However, no proven treatment based on cell transplantation is currently available for any brain disorder. Here, the history of cellular grafting is described from a clinical perspective, including some of the preclinical work that has formed the basis for its translation to patient application. The focus is on cell transplantation for Parkinson disease, which in many ways is paving the way for this field of research.

The continuous discovery of novel autoantigens and related neurologic disease has broadened the association in classical PNS to include conditions such as paraneoplastic cerebellar degeneration. It has also brought into focus several other neurologic syndromes with a putative neoplastic association. These conditions are overall rare, making it difficult to capture large numbers of patients to study, and raising the question of whether incidence is increasing over time or improved identification is driving the increased numbers of cases. With the rise and increasing use of immunotherapy for cancer treatment, the incidence of these conditions is additionally expected to rise and may present with various clinical symptoms.

Previously known as \"basilar\" or \"basilar artery\" migraine, it is an uncommon subtype of migraine with aura, one seen primarily in children, adolescents, and younger adults. The condition is characterized by migraine headache accompanied by several neurological symptoms conventionally assigned to dysfunction of brainstem structures. Initially felt to be vascular in origin, partly due to prevailing concepts of migraine pathophysiology at the time, most now believe the aura symptoms of migraine with brainstem aura are secondary to neural circuitry dysfunction. The differential diagnosis is reasonably broad, and most patients warrant investigation to exclude conditions bearing high degrees of morbidity and mortality. Neuroimaging, specifically brain MRI without contrast, is recommended for migraine with brainstem aura. Depending on the clinical presentation certain cases may require consideration of contrasted or vascular imaging, EEG, or lumbar puncture with cerebrospinal fluid analysis. Migraine prophylaxis should involve lifestyle adjustments and preventive medical therapies shown to be effective in clinical trials of migraine, following evidence-based guidelines.

In MS, activated B and T cells are recruited from outside the CNS, and contribute to inflammation, demyelination, and tissue damage inside the brain parenchyma. In the last decades, the treatment of MS has improved by the introduction of several disease-modifying therapies (DMTs). These drugs target generic mechanisms of lymphocyte activation and recruitment or deplete lymphocyte fractions from the circulation. This contributes to a suppression of relapses and new MS lesion formation on MRI. However, the impact on disability progression without relapses is much more variable. In addition, risk mitigation strategies are warranted to control for unwanted side effects of the attenuated immune competence induced by DMTs.
