Cell sensitivity, non-linearity and inverse effects.

It has been claimed that the homeopathic principle of 'similarity' (or 'similia') and the use of individualized remedies in extremely low doses conflicts with scientific laws, but this opinion can be disputed on the basis of recent scientific advances. Several mechanisms to explain the responsiveness of cells to ultra-low doses and the similarity as inversion of drug effects, have again been suggested in the framework of hormesis and modern paradoxical pharmacology. Low doses or high dilutions of a drug interact only with the enhanced sensitivities of regulatory systems, functioning as minute harmful stimuli to trigger specific compensatory healing reactions.

STAM protocol in dementia: a multicenter, single-blind, randomized, and controlled trial.

Background: The Sound Training for Attention and Memory in Dementia (STAM-Dem) is a manualized music-based protocol designed to be used in the rehabilitation of cognitive functions in elderly patients with dementia (PWD).

Method: This was a multicenter, single-blind, randomized, and controlled trial that involved 51 PWD. The objective was to test the STAM-Dem efficacy.
