The contribution of genetics to many neurological diseases is becoming increasingly apparent, and so it is imperative to stay up-to-date with these conditions. The 31 chapters in this volume cover a wide range of inherited conditions including forms of dystonia, Parkinson disease, spastic paraplegias, mitochondrial diseases, myopathies, neuropathies, and much more. Particular attention is paid to practical issues regarding how to make a genetic diagnosis and how to counsel the family. We will also address some contemporary issues in neurogenetics, such as the impact of direct-to-consumer genetic testing.
