Einleitung: Zur Therapie des IIH stehen grundsätzlich konservative (Gewichtsreduktion und Medikamente, z.B.: Acetazolamid, Topiramat, repetitive Lumbalpunktionen) und chirurgische (lumbo- oder ventrikulo-peritonealer Shunt, Ventrikulostomie, Opticusscheidenfensterung) bzw. in neuerer Zeit auch [zum vollständigen Text gelangen Sie über die oben angegebene URL], Symposium Idiopathische Intracranielle Hypertension (Pseudotumor cerebri)

Zusammenfassung Unter einer Meningitis versteht man eine Entzündung von Pia mater und Arachnoidea. Das Erregerspektrum ist weit und reicht von Bakterien, die hämatogen-metastatisch, fortgeleitet oder durch offene Hirnverletzung zur eitrigen Meningitis führen, über Viren zu Pilzen und Parasiten. Insbesondere bei den unbehandelt häufig letal verlaufenden eitrigen Meningitiden ist eine rasche Diagnose mit Erregernachweis notwendig. Unverzüglich ist daraufhin eine spezifische, der regionalen Resistenzentwicklung angepasste Therapie einzuleiten. Die meningeale Affektion im Rahmen einer Listeriose oder Tuberkulose verdient aufgrund des klinischen Bildes, des Verlaufs und der spezifischen Therapie besondere Beachtung. Die fungalen Infektionen werden, da klinisch häufig als Meningoenzephalitis imponierend, in Abschn. 33.3 abgehandelt.

Human immunodeficiency virus (HIV)-associated polyneuropathy has become the most common neurological complication of HIV infection and is one of the main risk factors for development of a neuropathy worldwide. Therefore HIV should always be considered as an underlying cause in patients with neuropathy. Many types of peripheral neuropathies are seen in HIV infection depending on the stage of infection. The inflammatory demyelinating neuropathies both acute (Guillain-Barre syndrome, GBS) and chronic (chronic inflammatory demyelinating neuropathy, CIDP) occur mainly at the time of seroconversion or early in the course of the disease while syndromes associated with opportunistic infections like CMV (i.e. polyradiculoneuropathy) occur in the late phase of HIV infection and are related to the loss of immune function. Distal symmetrical polyneuropathy (DSP) is the most common neuropathy in HIV-infected patients. We review the clinical manifestations, epidemiology, clinical diagnostics, pathophysiology and management strategies for HIV-associated polyneuropathies.

Many practical clinical questions regarding the management of human immunodeficiency virus (HIV)- associated neurocognitive disorder (HAND) remain unanswered. We sought to identify and develop practical answers to key clinical questions in HAND management. Sixty-six specialists from 30 countries provided input into the program, which was overseen by a steering committee. Fourteen questions were rated as being of greatest clinical importance. Answers were drafted by an expert group based on a comprehensive literature review. Sixty-three experts convened to determine consensus and level of evidence for the answers. Consensus was reached on all answers. For instance, good practice suggests that all HIV patients should be screened for HAND early in disease using standardized tools. Follow-up frequency depends on whether HAND is already present or whether clinical data suggest risk for developing HAND. Worsening neurocognitive impairment may trigger consideration of antiretroviral modification when other causes have been excluded. The Mind Exchange program provides practical guidance in the diagnosis, monitoring, and treatment of HAND.

After the introduction of highly active antiretroviral therapy (HAART) in 1996 the neurological manifestations of human immunodeficiency virus (HIV-1 )-infection did not decline in incidence and prevalence like the other complications of immunodeficiency; in contrast, due to the longer survival times of HAART treated HIV-1-positive individuals, prevalence of virus associated neurological disease increased during the last years, as international studies underline. Therefore, clinicians and HIV-therapists should be able to diagnose HIV-1-associated neurological disease even in early stages. This article describes symptoms and signs, neuro-imaging and cerebrospinal fluid findings as well as therapy options in primary HIV-1-associated neurological disease like encephalo- and myelopathy and polyneuropathy. Furthermore, those opportunistic infections, caused by bacteria, viruses other than HIV and parasites emerging with manifest immunodeficiency and remaining to be relevant in the HAART era are presented from diagnostic, differential-diagnostic and therapeutic points of view. An extra paragraph describes the interaction of HAART with neurological/psychiatric standard therapies.
