Abstract: Neurodegenerative diseases are a diverse group of diseases that are now one of the leading
causes of morbidity in the elderly population. These diseases include Alzheimer’s disease
(AD), Parkinson’s disease (PD), Huntington’s disease (HD), Amyotrophic Lateral Sclerosis (ALS),
etc. Although these diseases have a common characteristic feature of progressive neuronal loss
from various parts of the brain, they differ in the clinical symptoms and risk factors, leading to the
development and progression of the diseases. AD is a neurological condition that leads to dementia
and cognitive decline due to neuronal cell death in the brain, whereas PD is a movement disorder
affecting neuro-motor function and develops due to the death of the dopaminergic neurons in the
brain, resulting in decreased dopamine levels. Currently, the only treatment available for these neurodegenerative
diseases involves reducing the rate of progression of neuronal loss. This necessitates
the development of efficient early biomarkers and effective therapies for these diseases. Long
non-coding RNAs (LncRNAs) belong to a large family of non-coding transcripts with a minimum
length of 200 nucleotides. They are implied to be involved in the development of the brain, a variety
of diseases, and epigenetic, transcriptional, and posttranscriptional levels of gene regulation. Aberrant
expression of lncRNAs in the CNS is considered to play a major role in the development and
progression of AD and PD, two of the most leading causes of morbidity among elderly populations.
In this mini-review, we discuss the role of various long non-coding RNAs in neurodegenerative
diseases, such as Alzheimer’s and Parkinson’s disease, which can further be studied for the development
of potential biomarkers and therapeutic targets for various neurodegenerative diseases.
