To assess the effect of neurobehavioral dysfunction on amyotrophic lateral sclerosis (ALS) survival and on the use of life-prolonging therapies in a population-based setting.

To assess the effect of eligibility criteria in amyotrophic lateral sclerosis (ALS) clinical trials on the representativeness of the enrolled population.

A neuroprotective effect of lithium in amyotrophic lateral sclerosis (ALS) has been recently reported. We performed a multicenter trial with lithium carbonate to assess its tolerability, safety, and efficacy in patients with ALS, comparing 2 different target blood levels (0.4–0.8 mEq/L, therapeutic group TG, vs 0.2–0.4 mEq/L, subtherapeutic group STG).

The immune system has been found to be involved with positive and negative effects in the nervous system of amyotrophic lateral sclerosis (ALS) patients. In general, T cells, B cells, NK cells, mast cells, macrophages, dendritic cells, microglia, antibodies, complement and cytokines participate in limiting damage. Several mechanisms of action, such as production of neurotrophic growth factors and interaction with neurons and glial cells, have been shown to preserve these latter from injury and stimulate growth and repair. The immune system also participates in proliferation of neural progenitor stem cells and their migration to sites of injury and this activity has been documented in various neurologic disorders including traumatic injury, ischemic and hemorrhagic stroke, multiple sclerosis, infection, and neurodegenerative diseases (Alzheimer's disease, Parkinson's disease and ALS). Many therapies have been shown to stimulate the protective and regenerative aspects of the immune system in humans, such as intravenous immunoglobulins, and other experimental interventions such as vaccination, minocycline, antibodies and neural stem cells, have shown promise in animal models of ALS. Consequently, several immunosuppressive and immunomodulatory therapies have been tried in ALS, generally with no success, in particular intravenous immunoglobulins. The multiple aspects of the immune response in ALS are beginning to be appreciated, and their potential as pharmacologic targets in neurologic disease is being explored.

Recently hyperlipidemia was reported to be related to a significantly better outcome in amyotrophic lateral sclerosis (ALS). To investigate this, we evaluated the status of blood lipids in a large Italian series of patients with ALS, and assessed the effect of hyperlipidemia on patients’ survival.

To evaluate the modification of quality of life (QoL) and depression in a series of amyotrophic lateral sclerosis (ALS) patient–caregiver couples during a period of 9 months and compare them to patients’ ALS Functional Rating Scale (ALS-FRS).
