Drug and Disease Effects in Parkinson's Psychosis: Revisiting the Role of Dopamine.

Movement disorders clinical practice

Dave S, Weintraub D, Aarsland D, Ffytche DH.
PMID: 31970209
Mov Disord Clin Pract. 2019 Nov 11;7(1):32-36. doi: 10.1002/mdc3.12851. eCollection 2020 Jan.

BACKGROUND: Levodopa and dopamine agonists (dopamine replacement therapy [DRT]) are implicated in Parkinson's disease psychosis (PDP), but the relationship between DRT and neurotransmitter dysfunction inherent to PD remains unclear.OBJECTIVES: To examine the relationship between baseline striatal dopamine transporter (DAT)...

Think sight loss, think Charles Bonnet syndrome.

Therapeutic advances in ophthalmology

Best J, Liu PY, Ffytche D, Potts J, Moosajee M.
PMID: 31903448
Ther Adv Ophthalmol. 2019 Dec 20;11:2515841419895909. doi: 10.1177/2515841419895909. eCollection 2019.

An asymmetry of translational biological motion perception in schizophrenia.

Frontiers in psychology

Hastings CN, Brittain PJ, Ffytche DH.
PMID: 23882242
Front Psychol. 2013 Jul 16;4:436. doi: 10.3389/fpsyg.2013.00436. eCollection 2013.

BACKGROUND: Biological motion perception is served by a network of regions in the occipital, posterior temporal, and parietal lobe, overlapping areas of reduced cortical volume in schizophrenia. The atrophy in these regions is assumed to account for deficits in...

Localised increase in regional cerebral perfusion in patients with visual snow syndrome: a pseudo-continuous arterial spin labelling study.

Journal of neurology, neurosurgery, and psychiatry

Puledda F, Schankin CJ, O'Daly O, Ffytche D, Eren O, Karsan N, Williams SCR, Zelaya F, Goadsby PJ.
PMID: 34261750
J Neurol Neurosurg Psychiatry. 2021 Sep;92(9):918-926. doi: 10.1136/jnnp-2020-325881. Epub 2021 Jul 14.

OBJECTIVES: We aimed to investigate changes in regional cerebral blood flow (rCBF) using arterial spin labelling (ASL) in patients with visual snow syndrome (VSS), in order to understand more about the underlying neurobiology of the condition, which remains mostly...

Cognitive and visual processing performance in Parkinson's disease patients with vs without visual hallucinations: A meta-analysis.

Cortex; a journal devoted to the study of the nervous system and behavior

Montagnese M, Vignando M, Ffytche D, Mehta MA.
PMID: 34864505
Cortex. 2021 Nov 12;146:161-172. doi: 10.1016/j.cortex.2021.11.001. Epub 2021 Nov 12.

IMPORTANCE: Cognitive and visual impairments in Parkinson's Disease Psychosis (PDP) raise the question of whether a specific profile of impaired cognition and visual function is linked to vulnerability to visual hallucinations (VHs). Previous studies have limited sample sizes and...

Disrupted connectivity within visual, attentional and salience networks in the visual snow syndrome.

Human brain mapping

Puledda F, O'Daly O, Schankin C, Ffytche D, Williams SC, Goadsby PJ.
PMID: 33448525
Hum Brain Mapp. 2021 May;42(7):2032-2044. doi: 10.1002/hbm.25343. Epub 2021 Jan 15.

Here we investigate brain functional connectivity in patients with visual snow syndrome (VSS). Our main objective was to understand more about the underlying pathophysiology of this neurological syndrome. Twenty-four patients with VSS and an equal number of gender and...

Cognition, hallucination severity and hallucination-specific insight in neurodegenerative disorders and eye disease.

Cognitive neuropsychiatry

Montagnese M, Vignando M, Collerton D, Ffytche D, Mosimann UP, Taylor JP, daSilva Morgan K, Urwyler P.
PMID: 34338592
Cogn Neuropsychiatry. 2021 Aug 02;1-17. doi: 10.1080/13546805.2021.1960812. Epub 2021 Aug 02.

INTRODUCTION: Hallucinations occur across neurodegenerative disorders, with increasing severity, poorer cognition and impaired hallucination-specific insight associated with worse outcomes and faster disease progression. It remains unclear how changes in cognition, temporal aspects of hallucinations, hallucination-specific insight and distress relate...
