Over the past ten years much of Professor Love's research has focused on the pathogenesis of nerve cell damage and death in neurological disease - Alzheimer's disease in particular. Together with Dr Patrick Kehoe, he leads the Dementia Research Group, a part of the Institute of Clinical Neurosciences. He is Head of Section of Clinical Neurosciences in the School of Clinical Sciences, Faculty of Medicine and Dentistry.
Most of Seth's current research is in Alzheimer's disease, Lewy body dementia and vascular dementia, and concerns the pathogenesis and consequences of reduced cerebral blood flow in the different forms of dementia, the metabolism and clearance of Aβ and α-synuclein, and the molecular interrelationships between Alzheimer's disease, Lewy body diseases and vascular dementia. His research is currently supported by the Medical Research Council, Alzheimer's Research UK, the Alzheimer's Society, the British Heart Foundation and BRACE (Bristol Research into Alzheimer's and Care of the Elderly).

Recent key findings of the Dementia Research Group include the following:
- The expression of endothelin-converting enzyme-2 (which catalyses the production of the potent vasoconstrictor endothelin-1) is up-regulated by Aβ and increased in Alzheimer’s disease.
- In Alzheimer's disease phosphorylated tau binds and sequesters pSmad3 translocation, an intracellular mediator of TGFβ signal transduction, potentially interfering with the transcription of a range of TGFβ target genes.
- Picalm, a protein essential for clathrin-mediated endocytosis and the product of a gene recently shown in recent genome-wide association studies to be linked to Alzheimer's disease, is abundantly expressed by cerebrovascular endothelial cells, where it may be involved in the transport of Aβ across vessel walls and into the bloodstream.
- The activity of Aβ-degrading enzymes neprilysin, insulin-degrading enzyme and angiotensin-converting enzyme, and the activity of BACE-1 (the rate-limiting enzyme in Aβ production) are all elevated in the brain in Alzheimer’s disease and increase with normal ageing.
- In contrast to insoluble Aβ, the concentration of which increases with age and is signiﬁcantly higher in the brain in Alzheimer’s disease than age-matched controls, levels of total soluble and oligomeric Aβ normally decline with age and are signiﬁcantly higher in younger adults than older adults with or without Alzheimer’s disease.
