Loneliness and Neurobiology in
People with Schizophrenia
Introduction
Method
Results, Continued
- My intensive literature review included studies
and reviews published from 2015 to 2021, including databases like Pubmed and the BU Library
- Compared to neurotypical adults, people
with schizophrenia have reduced white
matter volume associated with deficits in
social skills and social cognition (Chee et al,
2020).
Results
- Schizophrenia is characterized by a set of positive
and negative symptoms.
- It interferes with a person’s ability to think clearly,
manage emotions, make decisions, and relate to others
(NAMI, n.d.)
- A particular study found that patients with
schizophrenia experienced higher levels of
loneliness than controls independently of their
objective social isolation (Trémeau et. al, 2016).
- In people with schizophrenia, reduced
activity in the amygdala is associated with
deficits in overall motivation and number
of social interactions (Chee et. al, 2020)
- Loneliness is highly prevalent in people
with schizophrenia compared to
neurotypical adults.
Loneliness has a direct relationship to
detrimental health outcomes and
mortality.
Discussion
Objectives
- How prevalent is loneliness and how does it differ
in people with schizophrenia compared to
neurotypical adults?
- What are some neurobiological structural and
functional differences in people with schizophrenia
that are related to loneliness and social interactions?
(Campellone et al., 2018)
- As demonstrated here, people with
schizophrenia tend to place less trust, anticipate
less pleasure, and expend less effort to increase the
likelihood future interactions with positive social
outcomes (Campellone et al., 2018), likely
contributing to experienced loneliness.
- Additionally, people with schizophrenia also
expend less effort to decrease the likelihood of
future interaction after a negative social outcome.
- More studies need to do momentary assessment
given the ever-varying nature of feeling loneliness
owing to the symptoms and difficulties experienced
by people with schizophrenia.
- Future studies need to further research strong,
unique neurobiological patterns in people with
schizophrenia, in the hope of identifying it earlier and
developing more effective early intervention
techniques.
