Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_train_141 ( "id" int, "gender" string, "hypothyroidism" bool, "depression" bool, "mini_mental_state_examination_mmse" int, "neuropsychiatric_diagnoses" bool, "memory_box" float, "early_stage_ad" bool, "head_injury" bool, "stroke" bool, "body_weight" float, "major_medical_illness" bool, "rbans_dmi" int, "psychosis" bool, "alzheimer_disease_ad" bool, "diabetes" bool, "body_mass_index_bmi" float, "ad" bool, "hypertension" bool, "clinical_dementia_rating_cdr" float, "age" float, "NOUSE" float )

### Question ###
male or female between the ages of 55 and 85 years with a clinical diagnosis of early stage ad, defined according to the following criteria assessed during screening and at baseline : clinical dementia rating ( cdr ) score of 0.5 or 1 with memory box score of 0.5 or greater ; mmse score of 20 or greater ; rbans dmi score <= 85

### Accurate SQL ###

SELECT * FROM table_train_141 WHERE (gender = 'male' OR gender = 'female') AND (age >= 55 AND age <= 85) AND early_stage_ad = 1 OR (clinical_dementia_rating_cdr = 0.5 OR clinical_dementia_rating_cdr = 1 AND memory_box >= 0.5) OR mini_mental_state_examination_mmse >= 20 OR rbans_dmi <= 85
