ALS or ALS mimic by neuroborreliosis-A case report.

Comprehensive investigation in motor neuron disease is vital not to miss a treatable differential diagnosis. Neuroborreliosis should be considered during an ALS work-up. However, false-positive CSF results do occur, and thus, results should be interpreted carefully in context of all clinical test results.

Altered motor plasticity in an acute relapse of multiple sclerosis.

In relapsing-remitting MS (RRMS), the symptoms of a clinical relapse subside over time. Neuroplasticity is believed to play an important compensatory role. In this study, we assessed excitability-decreasing plasticity during an acute relapse of MS and 12 weeks afterwards.
