In February 2011, rapid improvement in cognition; improvement in chronic neurological dysfunction; and reduction in chronic, intractable post-stroke pain was noted among a series of three patients treated off-label 13, 25, and 36 months after stroke with a single dose of etanercept, administered by perispinal injection [ 4].
There may be benefits within these domains as a result of training that would be apparent if measured on more specific standardised tasks, but may not lead either to general cognition improvement, or improvements may not be seen on measures such as the MMSE or ADAS-Cog which may not be sufficiently sensitive to change.
Van den Winckel et al's [ 42] intervention entailed exercise to music: in their view, the music was an essential component of the cognition improvements that were shown by participants.
Our hypotheses include reduction of socially phobic symptoms and dysfunctional cognitions, improvements in anxiety coping, interaction frequency and comorbid symptoms.
The cognitive improvement observed in our cohort supports the results obtained in the neurocognitive component of the CATIE trial [ 15] and in a recent naturalistic study [ 40], which reported an improvement in cognition after six months of continuous treatment with APDs.
For cognition, an improvement of at least 4 points on the ADAS-cog is generally regarded as clinically relevant.
For cognition, significant improvement from baseline was observed in working memory and verbal memory, although not in processing speed.
Reviews of randomised controlled trials (RCTs) of internet interventions with therapist assistance for depressive and anxiety disorders have found reductions in symptoms, relevant cognitions and improvement in patients' mental health literacy [ 37– 37].
We also hypothesize that melatonin will improve cognition reflected as improvements in neurocognitive and psychophysiological measures; that melatonin will improve sleep efficiency and subjective sleep quality; and that melatonin will reduce withdrawal symptoms.
Furthermore, reductions in hyperglycemic fasting glucose levels were accompanied by corresponding improvements in cognition, whereas significant improvements in FPI levels were not during a 24-week trial (4).
28 In another pilot 3-month program consisting of cognitive stimulation, physical activity, and socialization, the intervention group demonstrated stability of cognition and marked improvement in apathy, mood, and QoL compared to a control group.
