Abstract
This study was a within-group, simple random 2-block design to investigate the effect of the cognitive intervention on cognitive performance in blind patients. Thirty blind patients who expressed an interest in participation in the study were recruited from government a specialized school for the blind, 15 visually impaired individuals, and 30 individuals with normal vision from Foundation University School of Science and Technology, totaling 60 participants. between November 2023 and January 2024. They then undergo a standardized psychological assessment and were scheduled to undergo Cognitive test that are specially design for the blind. All participants met preserved general cognitive function (mini-mental state examination (MMSE) score of >24/30), and do not meet the diagnosis of dementia (according to the 10th International Statistical Classification of Diseases and Related) Health Problems (ICD-10).Other inclusion criteria were as follows: males and females with an average age of 30 years (range:18 to 60).In order to be included in the study, the participants had to be diagnosis of visual impairment and blind as evaluated by an eye specialist, primary school education (≥5 years), a Dementia scale and Beck depression Inventory. Exclusion criteria were that participant not be normal and younger than 18 years or older than 60, not have psychiatric disorders listed in the Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-v), current pharmaceutical regiment, including cognitive enhancers or antidepressants, and any physical condition that could preclude regular attendance and full participation in the intervention program. The present study was approved by the ethics committee of Foundation University School of Science and Technology, Islamabad, Pakistan. All participants were fully informed regarding the study protocol and provided written informed consent. This study aims to investigate the impact of digit span and rest on the cognitive abilities of individuals who are blind or visually impaired, utilizing cognitive tests as an assessment of intellectual functioning. The intervention's efficacy in potentially ameliorating levels of dementia, depression, and cognitive impairment is explored through a rigorous research methodology. The findings seek to establish psychometric property of Blind cognitive Intelligence test and study the effect of cognitive functioning and the onset of dementias and depression in blind individuals, offering valuable insights into the intervention's effectiveness in enhancing overall cognitive function.

Primary Outcomes

Primary Outcomes (end points)
Blind Cognition is primary outcome of the study.
Primary Outcomes (explanation)
Blind cognition is measure through BCIT and MMSE .The 72 item BCIT was administered by performing each task in a lab . Each participant was first asked to fill in a consent form and answer demographic questions before preceding to answering the BCIT. The BCIT was the first of a series of task to be perform by the participants. The remaining half item of task were always presented after the digit span and rest.

Secondary Outcomes

Secondary Outcomes (end points)
secondary outcomes are Depression and Dementia
Secondary Outcomes (explanation)
Depression is measure through The Beck Depression Inventory (BDI, BDI-II), created by Dr. Aaron T. Beck, it’s a 21-question multiple-choice self-report inventory, one of the most widely used instruments for measuring the severity of depression. Its development marked a shift among health care professionals, who had until then viewed depression from a psychodynamic perspective, instead of it being rooted in the patient’s own thoughts. Dementia is measure through Dementia scale
