By Oliver Sacks
Oliver Sacks vuelve a hacer gala de su singular talento como narrador, su sentido del humor y su inmensa cultura para plantear cuestiones que ponen en entredicho nuestra percepción del mundo y, muchas veces, nuestra propia identidad. Desde las visiones religiosas y su explicación fisiológica hasta el uso de drogas psicodélicas como puerta a una percepción inside que los sentidos nos niegan, los relatos del healthcare professional Sacks van más allá del mero historial médico y constituyen una auténtica historia cultural de los angeles percepción, un estudio antropológico de una supuesta anormalidad que no es, en el fondo, más que el reverso de lo que normalmente conocemos como realidad. «Fascinante. los angeles comprensión del health care provider Sacks hacia sus pacientes y su perspectiva filosófica transforman simples casos clínicos en relatos que iluminan las complejidades del cerebro humano y los misterios de l. a. mente humana» (Michiko Kakutani, ny Times).

Cross-pollination with ideas, theories, and experimental data from research on other neurodegenerative diseases (such as Alzheimer disease) or even from basic research in disciplines as diverse as chemical engineering and nanotechnology, greatly facilitated by the widespread use of the Internet, has opened new avenues to explore.
This barrier is a system of specialized cells and processes designed to keep the brain safe from toxins and infections. The blood–brain barrier is therefore a very good thing, but it does make it trickier for doctors to help patients with brain disorders like Parkinson disease, because dopamine cannot cross it. In 1968, Dr. George C. ” Based on laboratory research, Cotzias suggested treating Parkinson’s patients with high doses of levodopa (or l-dopa) because levodopa crosses the blood–brain barrier and the neurons can convert levodopa into dopamine.
Researchers now believe that about one in three people with Parkinson disease will end up developing dementia. In addition, about one in three people with Parkinson disease will end up having to use a walker, wheelchair, or other gait assistive device. Patients with Parkinson disease are more likely to be admitted to a nursing home than the general population. Over the past few years, specialists treating Parkinson’s patients have become increasingly aware of these problems and have turned their attention to new research designed to address problems and symptoms that emerge in the later stages of the disease and for which no effective treatment is yet available.
