Isolation-Induced Cognitive Dissonance: Impacts of Lockdown on Memory Functions
In the wake of the global pandemic, the long-term effects of extended periods of social isolation on memory and brain function have become a subject of intense scientific study. Recent research indicates that the emotional stress experienced during lockdowns, coupled with disrupted brain networks, has led to measurable negative impacts on cognitive processes[1][3].
Chronic stress and sensory overstimulation, often a result of excessive screen time during lockdowns, can alter brain development and neuroplasticity. This results in changes to both gray and white matter volumes in the brain, which are closely associated with memory consolidation difficulties, impaired concentration, and orientation problems—characteristics similar to mild cognitive impairment (MCI)[2].
The pandemic has also exacerbated reduced access to social support and increased unemployment, further compounding mental health risks and cognitive decline[4]. The World Health Organization has acknowledged that loneliness caused by such restrictions impacts brain health and underscores the importance of social connection for cognitive function[5].
However, there is hope for reversing some of the damage. The plasticity of the brain suggests that some cognitive impairments from social isolation and stress can improve with targeted interventions. Cognitive rehabilitation, social reintegration, and reducing chronic stress are potential avenues to restore affected brain functions. However, prolonged or severe disruptions may require substantial, multidisciplinary intervention to recover fully[6].
During these challenging times, it's essential to prioritise self-care and mental health. Getting outside, even for a short walk on a balcony, can help reduce stress and improve mental health[7]. Engaging in exercise, meditation, mindfulness, yoga, or outdoor activities can also help manage stress during lockdown[8].
Socialising with loved ones, whether through phone calls, video chats, letter writing, or Zoom meetings, can help combat feelings of loneliness[9]. Hobbies remain important for mental health during lockdown and can serve as a form of self-care[10].
It's important to remember that when life returns to normal, most people's cognition is expected to recover[11]. The human brain, a complex mass containing 86 billion neurons connected by 100 trillion synapses, has an incredible capacity for resilience and adaptation[12].
In an effort to contribute to scientific research on brain aging and cognition, the our platform offers free online games that anyone 18 years of age or older can join[13]. By participating, individuals can help advance our understanding of the brain and its response to stress during lockdowns.
As we navigate these unprecedented times, it's crucial to remember the importance of social connection and the potential impact of prolonged isolation on our cognitive health. Integrated strategies that promote mental health, reduce stress, and foster social connections are key to mitigating the cognitive harms associated with social isolation during pandemics.

The long-term effects of extended periods of social isolation, as a result of the pandemic, have led to increased research into the connections between health-and-wellness, mental-health, and science, specifically regarding the impact on memory and brain function [1]. Engaging in activities that reduce stress and promote mental health, such as exercise, meditation, and socializing with loved ones, can help mitigate the cognitive harms associated with social isolation during these challenging times [7][9].
