Where normal aging ends and dementia hasn’t begun.
Thresholds MCI with Mathew is a student-run channel about mild cognitive impairment (MCI): clear videos, honest interviews, and the neuroscience behind memory. Made by a future neurologist, for the students learning alongside.

My name is Mathew Roshan, and I’m a high school freshman. I was born in Kerala, India, and now live in California. I want to become a neurologist, and my focus is mild cognitive impairment (MCI).
That focus comes from watching relatives who were lively, funny, and energetic lose the ability to manage everyday life as their cognition declined. Seeing it up close pushed me to learn how neurodegenerative conditions work. I’m just starting out, and I’m eager to find research opportunities and build a strong scientific foundation so that one day I can help slow cognitive decline.
Why this channel
I started this YouTube channel, and my work at a local senior home, to share what I learn with other students who are curious about how MCI works. I also want to help people understand what cognitive decline does, so families facing it can support their loved ones better. And I’m recording my findings so I can build on them later in my journey.
Mission
To bridge medical knowledge and genuine human relationships: to inform the public about MCI and explore how social interaction and mental stimulation might help slow it. This channel is meant to be a resource for families going through it, and what I learn at the senior home is my starting point for helping my own community. I also hope to connect with others who share this interest and move MCI research forward.
What to expect
About one video a month on MCI: scientific breakdowns, key takeaways, interviews with experts, and what I’m learning from professors, professionals, and my own research. You’ll also get honest updates on my growth in the field. Being a high schooler here gives me a unique chance to see and learn firsthand.

MCI in four points
The short version. Each point becomes a video.
What it is
A noticeable decline in memory or thinking that is greater than expected for a person’s age, yet does not stop them from managing daily life independently.
Not always a one-way road
Some people with MCI stay stable, some improve, and some go on to develop dementia. Causes and outcomes vary widely.
How it’s assessed
Clinicians combine history, cognitive screening tools such as the MoCA, an exam, and tests to look for treatable contributors.
Why it matters
Spotting it early opens the door to managing risk factors like blood pressure, sleep, hearing, and activity, and to planning ahead.
Interviews
Conversations with clinicians, researchers, caregivers, and students. First guests are coming soon.
